编写一个函数，以便下面的主程序可以被调用函数mph_and_minutes_to_miles（）的更简单的代码所替换。

miles_per_hour = float(input())
minutes_traveled = float(input())
hours_traveled = minutes_traveled / 60.0
miles_traveled = hours_traveled * miles_per_hour

print('Miles: %f' % miles_traveled)

这就是问题所在。

def mph_and_minutes_to_miles(miles_per_hour, minutes_traveled):
    minutes_traveled = float(input())
    hours_traveled = minutes_traveled / 60
    miles = (minutes_traveled / 60) * miles_per_hour

miles_per_hour = float(input())
minutes_traveled = float(input())

print('Miles: %f' % mph_and_minutes_to_miles(miles_per_hour, minutes_traveled))

TypeError：必须是真实的，而不是NoneType

添加此函数而不是您在问题中定义的函数，应该可以修复错误。

def mph_and_minutes_to_miles(miles_per_hour, minuted_traveled):
    hours_traveled = minutes_traveled / 60
    miles = hours_traveled * miles_per_hour
    return miles

因此，总代码如下所示：

def mph_and_minutes_to_miles(miles_per_hour, minuted_traveled):
    hours_traveled = minutes_traveled / 60
    miles = hours_traveled * miles_per_hour
    return miles

miles_per_hour = float(input())
minutes_traveled = float(input())

print('Miles: %f' % mph_and_minutes_to_miles(miles_per_hour, minutes_traveled))

这里有两个选项，只需替换以下选项中的一个即可

def mph_and_minutes_to_miles(miles_per_hour, minutes_traveled):

或

print('Miles: %f' % mph_and_minutes_to_miles(miles_per_hour))

def mph_and_minutes_to_miles(miles_per_hour, minutes_traveled):
    hours = minutes_traveled / 60.0
    miles = hours * miles_per_hour

    return miles

miles_per_hour = float(input())
minutes_traveled = float(input())

print('Miles: {:f}'.format(mph_and_minutes_to_miles(miles_per_hour, minutes_traveled)))

def mph_and_minutes_to_miles(miles_per_hour, minuted_traveled):
    
    hours_traveled = minutes_traveled / 60
    miles = (minutes_traveled / 60) * miles_per_hour
    return miles

miles_per_hour = float(input())
minutes_traveled = float(input())

print('Miles: %f' % mph_and_minutes_to_miles(miles_per_hour, minutes_traveled))
