operator.delitem

sequences

Item deletion: del a[b].

Syntax

operator.delitem(a, b)

Like del a[b] it supports slices: delitem(xs, slice(0, 2)) removes the first two items. A missing key raises KeyError — if the key may be absent use dict.pop(key, None). Deleting from the front of a list shifts every other item, so a queue is better served by collections.deque.

Examples

import operator
l = [1, 2, 3]
operator.delitem(l, 1)
print(l)   # → [1, 3]
