How to remove an element from a list by index

Question

How do I remove an element from a list by index in Python?

I found the list.remove method, but say I want to remove the last element, how do I do this?

Answer 1

Yet another way to remove an element(s) from a list by index.

a = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

# remove the element at index 3
a[3:4] = []
# a is now [0, 1, 2, 4, 5, 6, 7, 8, 9]

# remove the elements from index 3 to index 6
a[3:7] = []
# a is now [0, 1, 2, 7, 8, 9]

a[x:y] points to the elements from index x to y-1. When we declare that portion of the list as an empty list ([]), those elements are removed.
