Question

turns = [4, 6, 2, 8, 1, 9, 5, 5, 3, 7, 6, 8, 2, 4]
turns.append([1, 1, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4])
turns.append([4, 6, 2, 8, 1, 9, 6, 5, 3, 7, 6, 8, 2, 4]) 
turns.append([0, 0, 26, 24, 3, 7, 5, 4, 25, 25, 21, 21, 21, 21])
turns.append([0, 0, 0, 0, 7, 3, 8, 2, 0, 0, 29, 29, 29, 29])
turns.append([0, 0, 0, 0, 26, 24, 0, 0, 0, 0, 0, 0, 0, 0])

arrayValue = turns[j][i]
    if arrayValue == turnCurrently:

Error Message:
Traceback (most recent call last):
  File "D:/a45d32f947055690c690d94f88/TicTacToe", line 183, in <module>
    arrayValue = turns[j][i]
TypeError: 'int' object is not subscriptable

My question is essentially, I want to test if turns[j][i] is equal to turnCurrently but I keep running into this subscriptable problem, I haven’t been able to find this answered anywhere I think that this is a very important question. Thanks in advance,
Richard

Answer 1

It often helps a lot to print out the content of your variables to see what it happening:

>>> turns
[4, 6, 2, 8, 1, 9, 5, 5, 3, 7, 6, 8, 2, 4, [1, 1, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4], [0, 0, 26, 24, 3, 7, 5, 4, 25, 25, 21, 21, 21, 21], [0, 0, 0, 0, 7, 3, 8, 2, 0, 0, 29, 29, 29, 29], [0, 0, 0, 0, 26, 24, 0, 0, 0, 0, 0, 0, 0, 0]]

As you can see, the first few elements of that list are simple integers, but not a list of ints. So when j is small, it will select an int and try to apply [i] on it – which fails.

The solution in this case is to put the first elements into an extra list:

turns = [[4, 6, 2, 8, 1, 9, 5, 5, 3, 7, 6, 8, 2, 4]]
turns.append( … )

Another way would be to initialize your list as an empty list, and append the first sub-list as well:

turns = []
turns.append([4, 6, 2, 8, 1, 9, 5, 5, 3, 7, 6, 8, 2, 4])
turns.append( … )
