THANK YOU. I have been trying to figure out how to do this for days while watching multiple videos and they never explained it as simple as you. 👍🏽

I was stuck on a lab assignment for 2 days now - I was missing the nano bit - THANK YOU!!

Thank you! So many of the videos I've watched will completely skip over the basics and throw you into a complex IDE environment, which then gets me completely baffled. I appreciate this video gets you started on the command line, and better helped me to understand the PATH.

Hi, what do you do when your python script has a function that accepts an input, say fpath. How do you call the script from commandline with that input?

[samsmusichub]

(Windows) instead of executing the file...
python hello.py

...actually opens the file. Help.

[infoengineer]

Creating the empty file is optional at first, am I right? Can I skip it and just print, 'nano hello.py'?

[leonardobernaschina]

Mine reads the file but doesn't show any output! Does anybody know why is that?
