Learn how to solve TypeError: unsupported operand type(s) for -: ‘int’ and ‘str’ error.

In the code snippet above we are subtracting an integer from a string which is not possible and throws the error. we can solve this error by converting the price_pershirt variable value to integer by using int() method.

total_money = int(input("How much money you have? "))
Shirt_price = input("How many you bought? ")
price_pershirt = int(input("what is the price per shirt? "))
money_remaining = total_money - price_pershirt
print("You have ${} monney left.".format(money_remaining))

output

How much money you have? 500
How many you bought? 30
what is the price per shirt? 10
You have $490 monney left.
