      I kept getting a TypeError in a loop. Turned out I was modifying the list I was iterating over. Lesson learned: copy the list first!

      My code ran fine locally but failed on deployment. I missed adding a required package to requirements.txt.

      I had trouble with global vs. local variables. Took me a while to realize Python scopes aren’t always intuitive.
