Adding new keys to a dictioary-CodePudding

I am coding a game inventory and i have a error message in my add to inventory function. what i am trying to do here is create a new key if the item is not already in the dict and give it the value 1 and if the item is already in the inventory it increases its value by 1. Happy for any Help i get:D

def add_to_inventory(inventory, added_items):
for row in inventory:
    if added_items[row] not in inventory:
        inventory[added_items[row]] = 1
    if added_items[row] in inventory:
        inventory[added_items[row]]  =1

This is the error i get:

TypeError: tuple indices must be integers or slices, not str

CodePudding user response：

You are checking the index of an item with a string.

my_items = ('a', 'b', 'c')

my_items['a']
TypeError: tuple indices must be integers or slices, not str

Loop over added_items instead:

for item in added_items:
    if item in inventory:
        inventory[item]  = 1
    else:
        inventory[item] = 1
