Question

更具体地说，我想从里面调用函数get_hours_worked calc_gross_pay。我意识到另一种方法是将参数传递给calc_gross_pay，但我想知道我试图做的是否可行。我有一种感觉它没有。谢谢你的帮助。

def main():
#
    print("This employee's gross pay for two weeks is:",calc_gross_pay())


def get_input():

    def get_hours_worked():
        #get_hours_worked
        x = float(input("How many hours worked in this two week period?     "))
        return x

    def get_hourly_rate():
        #get_hourly_rate()

        y = float(input("What is the hourly pay rate for this employee? "))
        return y

def calc_gross_pay():
    #
    gross = get_input(get_hours_worked) * get_input(get_hourly_rate)
    return gross

main()

Answer 1

这是您的代码的重组版本。我们不是在get_hours_worked中定义get_hourly_rate和get_input，而是将它们定义为调用get_input的单独函数。

def get_input(prompt):
    return float(input(prompt))

def get_hours_worked():
    return get_input("How many hours worked in this two week period? ")

def get_hourly_rate():
    return get_input("What is the hourly pay rate for this employee? ")

def calc_gross_pay():
    return get_hours_worked() * get_hourly_rate()

def main():
    print("This employee's gross pay for two weeks is:", calc_gross_pay())

main()

How many hours worked in this two week period? 50
What is the hourly pay rate for this employee? 20.00
This employee's gross pay for two weeks is: 1000.0

正如PM 2Ring指出的那样，更好地改变层次结构本身。但是如果你想要相同的话，请按以下步骤操作：

def get_input():

    def get_hours_worked():
        x = float(input("How many hours worked in this two week period?     "))
        return x

    def get_hourly_rate():
        y = float(input("What is the hourly pay rate for this employee? "))
        return y

    return get_hours_worked, get_hourly_rate                         # IMP

def calc_gross_pay():
    call_worked, call_rate = get_input()                             # get the functions
    gross = call_worked() * call_rate()                              # call them
    return gross     


def main():
    print("This employee's gross pay for two weeks is:",calc_gross_pay())

    #How many hours worked in this two week period?  3
    #What is the hourly pay rate for this employee?  4
    #This employee's gross pay for two weeks is: 12.0

main()

从函数中调用另一个函数内部的函数
