Python用户输入和打印

Question

chargePerDay = 30.0
feeEachMile = 0.5
fuelPerGallon = 1.5

print("How many users are there?")
numberOfUsers = input()

for i in range(numberOfUsers):
    print('For user ' + i)

    print("Number of days")
    numberOfDays = input()

    print("Number of miles")
    numberOfMiles = input()

    totalRentalFee = (chargePerDay * float(numberOfDays)) + (feeEachMile * float(numberOfMiles))
    print('Hi user ' + i + ' Your total rental fee is ' + str(totalRentalFee))

当我运行它时它正在打印对于范围内的我(用户数):TypeError: 'str' 对象不能解释为整数

这是怎么回事？？请帮忙!

Answer 1

你输入的是一个字符串，你需要把它转换成一个整数:

numberOfUsers = int(input())
# ... rest of code
