For Lab 3 last night, I couldn't make my columns line up nicely as they were supposed to be for the speed ticket file. However, Dr. Stonedahl realized that the problem I was having had to do with the font I had in my Thonny program and not my actual code.
Make sure to go to options in your Thonny program and have your font to be consolas or courier new :) this worked for me last night.
