Elegant way to remove items from sequence in Python? [duplicate]

Answer 1

You can also iterate backwards over the list:

for name in reversed(names):
    if name[-5:] == 'Smith':
        names.remove(name)

This has the advantage that it does not create a new list (like filter or a list comprehension) and uses an iterator instead of a list copy (like [:]).

Note that although removing elements while iterating backwards is safe, inserting them is somewhat trickier.
