Let me tell you what happened the first time I wrote a loop. I wanted to print numbers from 1 to 10. Simple enough. I had just read about while loops. I thought I understood them. So I wrote this: number = 1 while number 10: print(number) I ran it. Numbers started printing. 1, 2, 3... wait. Same numbers? 1, 1, 1, 1, 1, 1, 1, 1... The terminal filled up. Lines kept coming.
