I'd like to work on a trading floor, but in all the job postings, I see that they require the following skills: Python and VBA.

What are these used for in trading? And how can I learn them?

I really don't have any basic knowledge of Python or VBA. Where should I start?

hi… im 2 years into uni and im learning python and want to get more familiar with ml. after a mandatory ai course at uni, i did 2 courses recently to familiarize myself with the concepts but when it comes to building my first serious project i face some hurdles.
when i did the courses and its exercises i could do most of it myself… but apart from it, it feels tough.

first is that i never learned code before ai, so idk how im supposed to learn that without it. i try not to rely on it, and use it as a tutor. i have asked ai to guide me and give hints so i can write it myself but there are several elements i just have no idea of. once i study it i understand, but how can i learn more effectively… my project is a classification project…

one more question. if i want a career in ai/ml, what are some skills recruiters look for? how to be able to look at any problem and solve it. if there’s any courses or advice you can give…

so, im building a little parsing script for a programming language im trying to build (no, i dont plan on keeping the entire interpreter in python), and i was coding the loop thats supposed to remove the comments from the input script, BUT, theres always this line, this specific line that the parser just has a soft spot for apparently, it wont remove a comment from that line no matter what. im really lost here, it still happens when i replace the comment, HOWEVER, when i separate the line from the rest, it somehow works???

emulator.py: (called emulator instead of interpreter as it will also emulate a suitable enviroment for running scripts in the future)
from sys import argv
import parser
import lexer

def main(File):

    # We first need to open the file in here, i would have made it open in the parser, but this feels fancier
    with open(File, "r") as File:
        File = File.read()

    # The parser gives us the broken down code, kinda like digestion (pre-processing would be a better term)
    ParsedProgram = parser.Parse(File)

    # breaks off here to print the result from the parser (an attempt at debugging)
    print(ParsedProgram)
    exit(0)

    # We then pass it into the lexer, giving us a little tree of the entire program
    ProgramTree = lexer.Parse(ParsedProgram)

if __name__ == "__main__":
    main(argv[1])

___________________________________________
parser.py:
# this is unfinished.. as you could probably tell

IgnoredSymbols = [";", "\t"]
MatchingSymbols = ["\"", "\'", "(", "{"]

def Parse(File):
    # Strip away anything unnecesarry
    for Symbol in IgnoredSymbols:
        File = File.replace(Symbol, "")

    # Separate the lines
    File = File.split("\n")

    # Remove all comments
    for Line in File:
        if Line.startswith("//"):
            print(Line)
            File.remove(Line)

    # Clean up empty indexes
    for Line in File:
        if Line == "":
            File.remove(Line)

    # From here on, i just assemble the file as-is and return it, (an attempt at debugging, again)
    # Re-assemble the file
    AssembledFile = ""
    for Line in File:
        AssembledFile += Line
        AssembledFile += "\n"

    return AssembledFile

EDIT: holy crap, i forgot to include the script im trying to parse, apologies

EDIT 2: ive discovered list comprehension... a concept which ive never bothered to learn until now, thanks everyone for the help, question answered!

This is a doubt I have about the differences between f-strings and the .format() method. Consider the following dictionary accesses in an f-string:

>>> example_dict = {"one" : "string with word", "1" : "string with number", 1 : "integer"}
>>> f"{example_dict['one']}"
'string with word'
>>> f"{example_dict['1']}"
'string with number'
>>> f"{example_dict[1]}"
'integer'

If I try to perform the same accesses with the .format() method, I can only perform the first and last example:

>>> "{0[one]}".format(example_dict)
'string with word'
>>> "0[1]".format(example_dict)
'integer'

I can't seem to find any way to access the "1" key using the .format() method. I came up with this example because I noticed the way .format() accesses dictionary keys is without the quotes around the key for string keys. The f-string is easily able to access all the dictionary keys so it's not an issue with the keys themselves.

How do I access the "1" key using the .format() method? Is this a fundamental difference between f-strings and the .format() method that cannot be overcome?

Hello everyone,

I'm currently creating a little project about learning the basics of Python, but the problem is that I still have some issues with Python code. I wanted to ask you, how can I send a signal to my executable if I open it remotely?

More clearly:

from pwn import * 
from ctype import CDLL 
import time

r = remote("./main") 
signal.signal(SIGTSTP)

How can I send the signal to ./main?

Thank you in advance for the answers!

Seriously need help rn

so I was taking a test where we had to write a python file for a simple task.I was using IDLE for this (as it was the tool provided) and after i finished I saved the file.But for some reason when i came back for the next test I couldn't open up IDLE

it just showed the error stated above , along with a link to the docs page

Now the issue is that I only have access to that particular pc once a week or so as it is a learning tool.I did ask my supervisor and they shifted me to spyder .... But i still don't get why idle doesn't open up ...

Anyways I need help troubleshooting

Limitations

1.I can't use the internet on that pc

2.I can't do anything too risky

3.I couldn't install or uninstall most stuff

4.I only have a limited amount of time

Would be really grateful if anyone managed to figure out what's going on

feel free to ask anything related to the file
Thanks in advance !

I'm sure this debate has been had 10,000 times on this thread already, but I'm wondering if this is a new take on it. Will give a bit of backstory:

I knit a lot and realised recently it would be really useful to display my colour work patterns on the touch bar of my mac pro so I could watch a film or something like that while knitting. You could then integrate a marker so you don't lose your place and it could show one row of knitting at a time. I've never coded a day in my life, but I did some research. Looks like I can use python and better touch tool to design my own program that can do something like this. A colour work pattern is nothing more than rows of black and white squares which can be expressed as 1s and 0s, so it doesn't seem to be too complicated a project.

I know I could go to Claude or something similar and ask it to design the program, but truth told I'm not sure I trust it entirely, and I have a bit of a problem still with the concept of asking AI to build me something. However, I don't see why Claude couldn't teach me python in a manner that directs me towards building this program. Rather than attempting to learn the whole of python until I feel like I understand enough to build it, I can ask Claude to design a step by step guide that happens to result in the program I want, I can vet what it's doing and attempt to understand it, and maybe learn some python.

As someone who is barely computer savvy though, I've got a few naïve questions about how reliable this is. Is Claude/ AI actually any good at writing code and as a teacher and can I trust it to be running said code on my computer. I don't know much about how my computer works but just staring at the terminal makes it seem vulnerable. I heard recently about a scam that directed people to type code into their computer terminal, is this any different or am I being silly?

Beyond this I'm curious as to whether people thing I'm being silly in doing any of this when I could just ask Claude to write the program, is asking Claude to teach me really any different in the end?

Operations analyst here. About a third of my week is just moving numbers between two systems that apparently will never talk to each other.

So yeah, I want to automate it.

I’m not trying to become a developer or switch careers at 38. I just want the four hour Tuesday task to become a script I run and then forget about.

I’ve got Boot dev, DataCamp and Automate the Boring Stuff on my list. But I’m having trouble figuring out which one actually makes sense for someone who wants to automate work tasks instead of learn coding for a new career.

What would you start with?

Hi!
I‘m trying to get some code into VS Code with Python but I need to also install the Python Package in my Computer of course before I can start using VSC.
The Problem is, when I went to the Python page, to Download the latest Version and open the installer, it tells me that my file is corrupt.
Is anyone Else facing this Problem?
Thanks in advance :)

Im not attempting to make a bot per say, i just want to see if i can get a discord message, and then do something with it.

So far, python hasnt recognized "discord" as a valid package to import.

Then again, i am coding on a phone, maybe thats the problem.

But first, i want to see about receiving a discord message into python, so i can write it to a file, and then i can do stuff with it.

Any help would be appreciated!

Hello, I'm a nextjs(react) fullstack developer, currently working in a company as a single developer on this position.

\---

In the near future I want to transfer to a big company / team to work on big, enterprise type projects and as we all know most of the worlds big softwares aren't made with ts/js, so i want to learn a mew programming language and follow a new path.

\---

I'm trying to make a choice between: Java, Python or going into mobile development with React Native.

\-

I was also thinking about RUST, but the market doesn't seem that big for it.

\-

I'm not that good with math and I also know that python is often used in companies for data analysis.

\---

I would appreciate any advice from you guys on helping me choose my next path.

Thank you!

My first Python project: Postman Clone

I’ve been working on a small project called postman_clone to practice Python and learn more about how APIs and HTTP requests actually work.

I didn’t start with all these features at once. I started with the basics, then kept adding things as I learned. I worked with functions, conditions, user input, JSON, error handling, and HTTP requests, and little by little the project started becoming more complete.

Right now, my project can handle:

• GET
• POST
• PUT
• DELETE
• JSON request bodies
• An optional header
• An optional query parameter
• Basic error handling for requests and JSON

There’s still a lot I want to improve. I want to make the code cleaner, add support for multiple headers and query parameters, improve the error handling, and make the whole thing feel more like an actual API testing tool.

I’m still learning, so I’m posting the code here to get some feedback from people who have more experience with Python.

If you see something I could improve, or if there’s something you think I should add next, I’d really appreciate the advice 🙌

This is still a work in progress, but I’m happy with how far I’ve gotten so far.

"Python Concurrency with asyncio" by Matthew Fowler is gold, because it explains not only "what" but also "why" and asyncio evolution over years, so with this knowledge I can look at any tutorial or AI slop and immediately determine if it's worth looking at or still relies on manual loop management etc. However, it was published in 2022 in times of Python 3.10 and no 2nd edition in sight. asyncio has evolved even further since then, with TaskGroups, timeouts, except* etc. Anything recent on circa same depth level as that book?

Hi. Anyone who can share any repositories online or resources that I can learn python? I have a background on it (predictive analysis in OR) but I'm more interesting on applying in automating my tasks at work.

To give you some background, I have a BCA degree and previously worked as a Junior Technical Support Engineer for 2.5 years, followed by about 2.5 years as a US IT Recruiter. I recently had to take a career break due to a family medical emergency, but I am now ready to get back into the tech industry. I’ve been researching different fields, but the rapid advancements in AI have left me a bit overwhelmed about which direction to take. I’m looking for a resilient, future-proof career path. Initially, I looked into Java, but it seems like a massive time investment to master right now. I am currently leaning toward learning Python and moving into Data Science, or potentially just diving straight into a Data Science roadmap. For those already in the industry, do you think this is a safe, long-term choice? I would also deeply appreciate any recommendations for courses or structured learning paths!

i am a begginer in python i wanna do some projects what u guess for me ?

I am learning Python for ML (machine learning). What kind of projects would you recommend to reinforce my knowledge?

I am working through Automate the Boring Stuff on chapter 12. I have written the Clipboard Recorded program as instructed from the book, but the pyperclip.paste() function does not populate content from the clipboard. When I run the application, it only shows content that I put into the pyperclip.copy() function from another terminal, but nothing from using CTRL+C or right-click and choosing copy.

import pyperclip, time
pyperclip.set_clipboard('xclip')
print('Recording clipboard... (Ctrl-C to stop)')
previous_content = ''
try:
       while True:
               content = pyperclip.paste()     # Get clipboard contents.

               if content != previous_content:
                       # If it's different from the previous, print it:
                       print(content)
                       previous_content = content

               time.sleep(0.01)        # Pause to avoid hogging the CPU.
except KeyboardInterrupt:
       pass

I added the pyperclip.set_clipboard('xclip') line myself as an attempt to get this to work, but it still doesn't.

When I run something like the following from the interpreter, I get similar results. The paste function will output any string that was passed to the copy function, but it will not output anything from using CTRL+C.

Xclip is installed. I'm running Debian 13 with KDE Plasma 6.3.6.

Edit to add: I can call pyperclip.copy() from the interpreter and then paste using CTRL-V to another application. I have also tried using xsel instead with similar results.

Final Edit: I resolved it. Apparently I'm using Wayland and needed to install wl-clipboard. I need to study up on my different display servers for Linux.

Thank you.

Day 6/100: Maze solver in Reeborg's World. Solved 3/4 test cases but hit an infinite loop on the 4th. Frustrated but didn't quit. Will retry tomorrow or move forward. Feeling the difficulty ramp but pushing through. It took me 5 hours literally will show up tomorrow to push through again any suggestions will be appreciated

CLint need a list of 40,000+ members from the ACR directory. Need Name, City, State, Zip, Specialty, Email, and Phone.
The directory/search results give me some of this information, but email, phone, address, Member Since, etc. appear to be available only on the individual member profile.

So I'm trying to figure out the best way to approach this in Python.

If I literally open/request every profile, that's 43k+ profile requests, which obviously makes me concerned about rate limits, blocking, or getting the account/IP banned.

I'm considering Python requests/BeautifulSoup or Playwright, but before attempting something this large I'd like some advice.

I have a Master’s in Data Science with a previous background in wet-lab biology. My programming experience mainly came through my MSc, so I don’t have a traditional CS background.
At this point, I can usually **understand Python code when I see it**, explain what it is doing, and modify parts of it. But if you give me a problem and ask me to write the solution from scratch, I struggle — and I often rely on ChatGPT to get started.
I’m trying to figure out what the right way to overcome this is.
Should I:
go back and systematically learn Python/CS fundamentals through tutorials first, then start projects?
or keep building bioinformatics projects and use ChatGPT as a tutor/coding assistant while gradually becoming more independent?
I find learning programming purely through tutorials quite difficult and passive, especially because I’ve never studied CS formally.
**For people who came into bioinformatics from biology rather than CS: how did you actually learn to code independently? What should I be able to do before I consider myself “good enough” at Python for a junior bioinformatics role?**

I am an AIML student currently in my 3rd year and want to know that for my placement preparation should I proceed with doing DSA in python or should I change my language to Java/C++

so I wrote a python program years ago in school, and I was wondering if anyone on here could take a look at it for me. I'd like to improve it so that it brings you back to the start or the previous choice with an option to return to the start, but I don't remember anything because it's been years since I touched python. Feel free to play the game and get a feel for it.

Anyone have a fix or advice to fix it? I'll link the code here so that y'all can try it out yourselves (eventually I want to port this game to Nintendo DS).

We have secretaries creating reservations in a SAP form. Those reservations get exported as CSV files into some shared directory each VM has to mount. Then a cronjob fires an automated python script that drops all the tables in the application, and shoves the data from the CSV into those rows.

The form fields in the SAP forms don't match the CSV row fields. The CSV row fields don't match the applications MySQL schema in type or name. Properties such as datetime, address, client, guests, room_number etc are split across 8-12 CSV files so you have to load all of them into memory and perform black magic to construct a proper reservation object.

No unique IDs are given (so I have to fingerprint based on time, client, address etc), dates are in non-standard string format, 50% of the data is redundant and even the damn encoding is not utf8.

It's been a week or two that I have been working on this and Its driving me crazy. The schema is so complex that it takes a good hour just to load up this convoluted mess into my mental RAM so I can start working on it at the start of the day.

I assume if I were a full-time ETL/PowerBI guy I'd already finish this nightmare but I'm a devops/fullstack guy. I need some guidance on how to think about this problem in an abstract sense (i.e how to organize garbage data) so I can handle it effectively.
