类型错误：第 8 行的 Sub 不支持的操作数类型：'str' 和 'int'

Question

为什么我一直得到这个答案？类型错误：Sub的操作数类型不受支持：第8行的"str"one_answers"int">

#Define payment, knowing that up to 40 hours it is normal rate, and above that every hour is paid at 150%.
totalHours = input("Enter the total amount of worked hours:n")
hourlyWage = input("Enter the payrate per hour:n")
if totalHours <= 40:
regularHours = totalHours
overtime = 0
else:
overtime = float(input(totalHours - 40))
regularHours = float(input(40))
payment = hourlyWage*regularHours + (1.5*hourlyWage)*overtime
print (payment)

Answer 1

在python3中，如果您提供输入，它只接受字符串形式的输入。您需要将其转换为int。此外，其他部分的输入是不必要的

#Define payment, knowing that up to 40 hours it is normal rate, and above that every hour is paid at 150%.
totalHours = int(input("Enter the total amount of worked hours:n"))
hourlyWage = int(input("Enter the payrate per hour:n"))
if totalHours <= 40:
regularHours = totalHours
overtime = 0
else:
overtime = float(totalHours - 40)
regularHours = float(40)
payment = hourlyWage*regularHours + (1.5*hourlyWage)*overtime
print (payment)

Answer 2

您需要添加int转换。

totalHours = int(input("Enter the total amount of worked hours:n"))
hourlyWage = int(input("Enter the payrate per hour:n"))

从input得到的是str，而不是int，所以不能用str和int进行数学运算。
