Awesome solution to a common problem, thanks Anthony. Don't know why this made me think of this, but would you be interested in covering the topic of relative imports? Maybe you already did but it was a topic that bugged me quite a bit. Merry Christmas!

Super handy trick. I almost always just pass __file__ directly into pathlib.Path, is there any danger in that. I had no idea that the absolute / relative path difference existed.

Wow, flask.__file__ is super useful, I wish I knew it before, it would've saved me a lot of annoying mouse clicks : }
Thank you for the video, Anthony!

Question . For what do you use PWD in python $PWD/t.py?

Merry Christmas Anthony,
Can you go over interprocess calls where a code like this (below)
can be used to control the stdin and stdout of the debugger from the parent process

process = Popen(['python', '-m', 'pdb', 'sample.py'], stdin=stdin, stdout=stdout) #Custom debugger that writes (n, s, l, p) and also reads output
Thanks
