Found out my code was running 60% slower because of one dumb habit
I was working on a Python script for a side project and it was taking forever to process a list of names. Turns out I was using a regular for loop with .append() instead of a list comprehension, and the difference was massive after I read a post on Stack Overflow. Has anyone else found a simple change that saved them way more time than expected?

Yeah, using .join() on strings instead of += saved me like 80% time once.
