How can I read inputs as numbers?（10个答案）
2年前关闭。

rent = int("300")
shopping = int("150")
clothes = int("200")
print("you have ", + cash, "dollars")
print("You have 3 options to spend your money")
print("$300 - Rent - 1")
print("$150 - Shopping - 2")
print("$200 - Clothes - 3")
choice = input("Enter a number between 1-3 to choose how you spend your money")

if choice == 1:
    print("you now have", cash - rent, "dollars")
elif choice == 2:
    print("you now have", cash - shopping, "dollars")

if/elif部分将不会打印包含在其中的内容。
