I finally understood why my loops kept breaking after a chat at the Denver library
I was trying to make a simple list of numbers in Python, but my code kept stopping early. A guy next to me at the library coding group pointed out I was changing the list while my loop was running through it. He said, 'You're removing items as you go, so the list gets shorter and the loop gets confused.' I had to make a copy of the list to loop over instead. Has anyone else run into this problem with for loops?

Yeah, that exact thing tripped me up for days once.

Days? That's actually insane.

@leo_thomas2 I read a blog post that said loops and list size changes just don't mix.
