Today I was meeting with a researcher in my department so that I could show him how the software I developed works. He graduated from a really good university in electronic engineering, with 100/100 I think, and he can manage to copy&paste some python code. So I didn't expect what happened today.
Guy: 'So I have to give to your program as input this python file which contains a function you need to call, right?'
Me: 'Yep, I mean, that is a jupyter notebook, I need a text file containing only the function which is in that notebook'
Guy: *Downloads the notebook, tries to feed the notebook file into my program*
Me: 'Wait, don't, there probably is a lot of junk related to jupyter notebook, try opening it in notepad++'
Guy: *Opens file, sees a lot of junk text*
Me: 'Yeah, I thought so, you need to save it as plain text or .py'
Guy: *Renames the notebook as .txt*
Me: *Shakes my head without him noticing*
'That won't work, the content of the file won't change like that...'
