A post was merged into an existing topic: How does Python decide the default sort order?


I’m trying to understand if the code I have below will become an issue in a real use scenario as opposed to what the correct solution was – I did not define a new variable in the for loop, i.e. “for number in start_list:”, the output was the same so I am not sure if this is very incorrect by me.


for start_list in start_list:

square_list.append(start_list ** 2)

print square_list


It’s way too soon to be worrying about that. Nothing we do at this stage is going to overburden the system. Concentrate on learning concepts and syntax, and not on the better way to do things. Stick to the lessons and don’t stray much. It’s counterproductive and disruptive.
