Thanks a lot, I'been struggling a lot trying to use pipreqs directly from a cmd promp but showing no results (I think it's because I'm working directly on a Sharepoint folder). This solution worked perfectly, thank you man!

Regarding venv, I understand it comes with python, but I've seen many manually install pyenv separately.. why, what's the difference between
1) pipx
2) venv / virtualenv
3) pyenv (not pyvenv ) with or without the virtualenv plugin (i.e. pyenv-virtualenv)

Also, is pipreqs smart enough to analyze my python script and determine that some imports are not actually used, and therefore won't add it to the requirements txt? I'd like to find a way to give it a script and have it report the versions the user will need.. ONLY for the packages that are used somewhere in the code!

Maybe it is a wrapper around pip freeze, that is where it pulls the versions from, just thinking, not sure

Thanks for the video. I was wondering if you could help me figure out how to automatically name new files with python? I have created a very basic tkinter app that allows users to enter a url into an input, and then once they press upload, that url will be saved as a PDF. The problem is the PDF always has the same name since it is manually placed within the script. How can I get python to change the name after every new submission (e.g. pdf1.pdf, pdf2.pdf, pdf3.pdf, etc)?
