How can I cut a list from given index

Question

Cut down the same list into given index

Let's say we have a list

mainList = [3,5,2,7,0,9]

If I remove 3 item then mainList should be

[7,0,9]

Is there a way to do that?

Answer 1

If you want to delete the first n occurences in a list:

mainList = [3,5,2,7,0,9]
for i in range(0,3):
    mainList.pop(0)
print(mainList)

Output:

[7, 0, 9]
