I have a very large list, and I'd like to iteratively remove the first 50 elements without copying it (as for example something like list[50:]).
My initial thought was by doing:
[list.pop(0) for i in range(50)]
What would be the most performant way to do this?
You can use the del keyword. So to remove the first 50 elements you can do:
del list[:50]
Update the list in place with a slice that removes the first 50 items:
list[:] = list[50:]
Update
I ran some timeit tests which actually show del list[:50] to be approx 2X faster.
