How to work with large lists without crashing Python?

[Corate]

I’m trying to import the list. Im just copying 10,000 elements into idle and hitting enter. Thats where it lags. it also lags when i print the list. If i make the list one element at a time it is fine, however I need to import a premade list. When I get home I can post the code, aorry for the inconvinence.
