Code returns TypeError and I'm not sure why

Question

The code below returns 'TypeError: 'int' object is not subscriptable' when move_pas is called. The thnig is, is that the code affecting this is also in move_ag, but when I call that there is no error and I cant figure out why that is. I'm running this in python3.9.2 in vscode if that matters. Thanks in advance. (sorry for bad english)

import random

The way that you have it:

def move_pas(amount_list, stance_list):
    if 'passive' in stance_list:
        for i in range(0, len(char_list)):
            if stance_list[i] == "passive":
                am = spot_list.count(spot_list[i])
                if am == 1:
                    stance_list[i] = 2
                    amount_list[spot_list[i]] -= 2
                elif am == 2:
                    if amount_list[i] == 1:
                        stance_list = 1 #------------------------- here
                        amount_list[spot_list[i]] -= 1
                    if amount_list[i] == 2:
                        stance_list = 1 #------------------------- here
                        amount_list[spot_list[i]] -= 1
                    if amount_list[i] == 0.5:
                        stance_list = 0.5 #----------------------- here
                        amount_list[spot_list[i]] -= 0.5

If any of the if statements is met the stance_list is changed to an integer (1 or 0.5). So the next time the loop goes on it will meet this statement if stance_list[i] == "passive" and will tell you that a integer cannot be subscripted (Which is to be expected).

I assume what you want to do is to change the i-th element of stance_list to that number. Like this:

def move_pas(amount_list, stance_list):
    if 'passive' in stance_list:
        for i in range(0, len(char_list)):
            print(stance_list)
            if stance_list[i] == "passive":
                am = spot_list.count(spot_list[i])
                if am == 1:
                    stance_list[i] = 2
                    amount_list[spot_list[i]] -= 2
                elif am == 2:
                    if amount_list[i] == 1:
                        stance_list[i] = 1 #------------------------- here
                        amount_list[spot_list[i]] -= 1
                    if amount_list[i] == 2:
                        stance_list[i] = 1 #------------------------- here
                        amount_list[spot_list[i]] -= 1
                    if amount_list[i] == 0.5:
                        stance_list[i] = 0.5 #----------------------- here
                        amount_list[spot_list[i]] -= 0.5
