4548 :: Python Modules & why Python is better

  ... with Nim. 🤪

  So some people chating about Python, and coming from Python to Nim, and etc.

  I will show you some stuff I done with Nim, on Python, and maybe works as an example implementation for people wanting to do the same.

  I wanted to speed up Python, everybody know is slow, and taking some functions that often slows down your scripts, they result on 4 ~ 20 times faster.

  pip install faster_than_requests

  https://github.com/juancarlospaco/faster-than-requests#faster-than-requests

  • Faster simple alternative to urllib.requests.

  pip install faster_than_csv

  https://github.com/juancarlospaco/faster-than-csv#faster-than-csv

  • Faster simple alternative to csv, some people doing data science seems to love this one.

  pip install faster_than_walk

  https://github.com/juancarlospaco/faster-than-walk#faster-than-walk

  • Faster simple alternative to os.walk().

  All code is there, so feel free to check how its done if you want to do the same.

  Uploaded to PyPI with the setup.py on that repo, with python setup.py sdist --formats=zip upload.

  The repo also provides a Dockerfile for people wanting to try it without installing it.

  Packages dont have any dependency at all, they are faster than Cython, while syntax still more readable.

  The real work is done by https://github.com/yglukhov/nimpy

  Please keep in mind that many people only read the title and this week's topic is "are we popular now? No? why?!"

  So "Python Modules & why Python is better" is a suboptimal headline. ;-)

  (This forum really needs an "edit title" feature...)

  Nice work, but I'm curious on what will happen if I import more than one of your packages in one python script. IIRC, I can't have multiple Nim GC instances in one process, otherwise the GC module will not behave properly and finally leads to crash.

  @litwt31 If you use nimrtl.dll there is only one instance of the GC'ed heap and things are supposed to work. Note that this problem isn't Nim specific or GC specific either, it's an inherent problem of shared libraries / DLLs.

  Yeah, that's my point. Maybe the nimrtl.dll approach should be taken for these python packages? I think it will probably bring back this issue.

  It's a clickbait title, people are unlikely to only read it and be convinced that "okay, Nim is worse than Python".
