r/Python on Reddit: Python open source projects to contribute
1 week ago -

Hi everyone,

I have around 1 year of professional experience with python as a backend developer, but I worked with python for hobby projects for a few years now. I'm looking for some small/medium size open source projects to contribute and keep expanding my skills. I would be interested to contribute continuously if there is a project that piques my interest. Some of my interests involve: Web development, AI and data processing. If you have anything suitable projects that welcome new contributors feel free to share them in the comments. If you want to see my personal GitHub profile you can dm me.
