TypeError: string indices must be integers in dictionary

Question

Why this code gives me typeError? And how can I call a dictionary using varible X? "TypeError: string indices must be integers" I print "espresso" in input. Thanks

machine = {"Water": 300, "Milk": 200, "Coffe": 100,}
espresso = {"Water": 50, "Milk": 0, "Coffe": 28,}


def check(x):
   
    z = machine["Water"] >= x["Water"]
    print(z)

x = input()
check(x)

it is checking if machine have enough water for input = espresso — Raullock _, Dec 13 '21 at 12:52
different types of coffe. In this case i have only ecspresso in dictionary. So X could be different input "espresso', "latte" and etc. — Raullock _, Dec 13 '21 at 12:57
``machine`` and ``espresso`` should themselves be key/value pairs in yet another, outer dictionary. — MisterMiyagi, Dec 13 '21 at 12:58
latte and other types of coffe will appera later. And Machine dictionary represent the resotces machine has to make coffe. Espresso dictionary represented the requirments to produce coffe. So they cant be key and value for one dictionary — Raullock _, Dec 13 '21 at 13:12

use dictionary for mapping. this question

machine = {"Water": 300, "Milk": 200, "Coffe": 100,}
espresso = {"Water": 50, "Milk": 0, "Coffe": 28,}


def check(x):
    d ={'espresso':espresso} 
    z = machine["Water"] >= d[x]["Water"]
    print(z)

x = input()
check(x)

yes. Could you please check again my message. I have edit it. The problem that I am calling to dictionary through function with input. – Raullock _ Dec 13 '21 at 12:36

-1

because x holds: x = "espresso" and it is not a dictionary as you call it... you can't ask x["Water"].

you need to change from: x = "espresso" to x = espresso
