I’m Flat out struggling to understand list indexes

[menator01]

In the fist list 2nd index, first index of inner list the value 3
if you wish to pull and index you do not do an assignment operation

Output:
>>> x = [0, 1, [2]]
>>> x
[0, 1, [2]]
>>> x[2]
[2]
>>> x[2][0]
2
>>> x[2][0] = 3
>>> x[2][0]
3
