My first real project in python

Hi, I'm 15 and I recently started python. For my firt project I did a calculator.

Here is the program:

num1=int(input("choisissez un nombre"))



num2=int(input("choisissez un nombre")) #sélection des nombres



operator=int(input("choisissez un operateur 1=+ ;2=- ;3=/ "))



if operator ==1:

result=num1+num2



elif operator ==2: #calcule

result=num1-num2



elif operator ==3:

result=num1/num2



print("voici votre résultat",result)


I'm here for advice on this program and more generally on python.

If you have little project like this I take too.

Thank you for reading.

R Segment Anything Model 3 (SAM 3) is released

Abstract: We present Segment Anything Model (SAM) 3, a unified model that detects, segments, and tracks objects in images and videos based on concept prompts, which we define as either short noun phrases (e.g., “yellow school bus”), image exemplars, or a combination of both. Promptable Concept Segmentation (PCS) takes such prompts and returns segmentation masks and unique identities for all matching object instances. To advance PCS, we build a scalable data engine that produces a high-quality dataset with 4M unique concept labels, including hard negatives, across images and videos. Our model consists of an image-level detector and a memory-based video tracker that share a single backbone. Recognition and localization are decoupled with a presence head, which boosts detection accuracy. SAM 3 doubles the accuracy of existing systems in both image and video PCS, and improves previous SAM capabilities on visual segmentation tasks. We open source SAM 3 along with our new Segment Anything with Concepts (SA-Co) benchmark for promptable concept segmentation.

whereproc: a small CLI that tells you where a running process’s executable actually lives

I’ve been working on some small, practical command-line utilities, and this one turned out to be surprisingly useful, so I packaged it up and put it on PyPI.

What My Project Does

whereproc is a command-line tool built on top of psutil that inspects running processes and reports the full filesystem path of the executable backing them. It supports substring, exact-match, and regex searches, and it can match against either the process name or the entire command line. Output can be human-readable, JSON, or a quiet/scripting mode that prints only the executable path.

whereproc answers a question I kept hitting in day-to-day work: "What executable is actually backing this running process?"

Target Audience

whereproc is useful for anyone:

debugging PATH issues
finding the real location of app bundles / snap packages
scripting around PID or exe discovery
process verification and automation

Comparison

There are existing tools that overlap with some functionality (ps, pgrep, pidof, Windows Task Manager, Activity Monitor, Process Explorer), but:

- whereproc always shows the resolved executable path, which many platform tools obscure or hide behind symlinks.
- It unifies behavior across platforms. The same command works the same way on Linux, macOS, and Windows.
- It provides multiple match modes (substring, exact, regex, command-line search) instead of

how obvious is this retry logic bug to you?

I was writing a function to handle a 429 error from NCBI API today, its a recursive retry function, thought it looked clean but..

well the code ran without errors, but downstream I kept getting None values in the output instead of the API data response. It drove me crazy because the logs showed the retries were happening and "succeeding."

Here is the snippet (simplified).



def fetchdatawithretry(retries=10):
try:
return apiclient.getdata()
except RateLimitError:
if retries > 0:
print(f"Rate limit hit. Retrying... {retries} left")
time.sleep(1)

fetchdatawithretry(retries - 1)

Flask-Security vs a la carte (login, authorize, dance)?

I've used flask-login for many years, bolting on my own roles/permissions system, email authentication, password management, etc. Am looking to finally make an upgrade to some standard tools, but am having trouble deciding between the all-in-one pallets project flask-security and an a la carte approach with flask-login, flask-authorize, and flask-dance (plus probably others).

Have you used either stack? What did you like/dislike about it?

Latest Python Podcasts & Conference Talks (week 47, 2025)

Hi r/Python!

As part of Tech Talks Weekly, I'll be posting here every week with all the latest Python conference talks and podcasts. To build this list, I'm following over 100 software engineering conferences and even more podcasts. This means you no longer need to scroll through messy YT subscriptions or RSS feeds!

In addition, I'll periodically post compilations, for example a list of the most-watched Python talks of 2025.

The following list includes all the Python talks and podcasts published in the past 7 days (2025-11-13 - 2025-11-20).

Why do we repeat type hints in docstrings?

I see a lot of code like this:



def foo(x: int) -> int:
"""Does something

Parameters:
x (int): Description of x

Returns:
int: Returning value
"""

return x


Isn’t the type information in the docstring redundant? It’s already specified in the function definition, and as actual code, not strings.

PyTogether - Google Docs for Python (free and open-source, real-time browser IDE)

For the past 4 months, I’ve been working on a full-stack project I’m really proud of called PyTogether (pytogether.org).



# What My Project Does

It is a real-time, collaborative Python IDE designed with beginners in mind (think Google Docs, but for Python). It’s meant for pair programming, tutoring, or just coding Python together. It’s completely free. No subscriptions, no ads, nothing. Just create an account, make a group, and start a project. Has proper code-linting, extremely intuitive UI, autosaving, drawing features (you can draw directly onto the IDE and scroll), live selections, and voice/live chats per project. There are no limitations at the moment (except for code size to prevent malicious payloads). There is also built-in support for libraries like matplotlib.

Source code: https://github.com/SJRiz/pytogether



# Target Audience

It’s designed for tutors, educators, or Python beginners.



# Comparison With Existing Alternatives

Why build this when Replit or VS Code Live Share already exist?

Because my goal was simplicity and education. I wanted something lightweight for beginners who just want to write and share simple Python scripts (alone or with others), without downloads, paywalls, or extra noise. There’s also no AI/copilot built in, something many teachers and learners actually prefer. I also focused on a communication-first approach, where the IDE

Can someone post an example of a flask app that has blueprints with multiple models.py in each blueprint folder using the current working version of flask with html as the front end ?

I am getting an error in my flask app rather then posting my long convoluted error I figure I would try to see if there something wrong with my app by seeing an working example of a flask app with html as the front end with blueprints with multiple models.py files in each blueprint folder using the current working version of flask. Does anyone have working example ? Could someone link there github or something else?

My web app was working before the multiple models.py files.
