PyCharm Community Édition would be worth looking at.

Can you please post a bit of code that demonstrates what you are seeing?

@cvp, Caution about leaving io.BytesIO() open after you are done with them. In a memory constrained environment like Pythonista and with large objects like images, running out of RAM can be a problem.

# attach photo to mail      
buf = io.BytesIO()
pil_image.save(buf, format='JPEG')
photo_data = buf.getvalue()

# might be safer rewritten:
with io.BytesIO() as buf:
    pil_image.save(buf, format='JPEG')
    photo_data = buf.getvalue()

https://pyto.app already has scikit-learn on Python 3.8 on iOS

#! /usr/bin/env python3

from random import shuffle


def make_card_deck(ranks=None, suits="CDHS") -> list:
    ranks = ranks or [str(n) for n in range(2, 11)] + list("JQKA")
    return [rank + suit for suit in suits for rank in ranks]


if __name__ == "__main__":
    decks = {color: make_card_deck() for color in "blue red yellow white".split()}
    print(decks)
    shuffle(decks["blue"])
    print(decks["blue"])
    print(make_card_deck("iOS Linux macOS Windows".split(), ".app .exe .py".split()))

https://cookiecutter.readthedocs.io/en/latest/readme.html#python is a tool that generates Python projects and their templates are models worth checking out

https://github.com/miniupnp/miniupnp clicking on the colored bar (just under the Commits) shows that Python is < 1% of the project. You could look at the 5 Python files (https://github.com/miniupnp/miniupnp/search?l=python) but most of the functionality will be in the 200+ C++ files. :-(

Here is a supersimple upnp Pythonista script that I wrote some time ago.
