Is there a list function that swaps two items in a list?

Question

Example:

Suppose that 'swap' is a list function:

list = ['a', 'b', 'c', 'd']
list.swap(0, 3)
print(list)

Output:
['d', 'b', 'c', 'a']

Answer 1

I don't think there is any built in swap function in python but
list [0], list [3] = list [3], list [0] should work
