Python程序不会在第一次用户输入之外执行 [英] Python program does not execute beyond first user input

问题描述

我编写了一个Python程序，我希望接受来自用户的y输入，如果用户输入y，则进行一些简单的计算并打印结果。

I have written a Python program that I expect to accept a "y" input from a user, and if the user inputs "y", do some simple calculations and print the results.

然而，即使输入是y，它也不会执行超过
的用户输入。请帮我找到程序中的错误。

However it is not executing beyond the user input even if that input is "y". Please help me locate the errors in the program.

代码是：

The code is:

#This function is to get the user to input the data needed to use in the rest of the program
#It should return the 3 variables name, hrs_wrkd, and payrate

def get_info(name,hrs_wrkd,payrate):
    print('is this working?');
    name = input('What is the last name of the employee?');
    hrs_wrkd = float(input('How many hours did',name,' work last week?'));
    payrate = float(input('How much does',name,' get paid?'));
    return name,hrs_wrkd,payrate
#This function should be to calculate the employee's regular pay hours
#It accepts arguments from get_info

def calculate_reg_pay(hrs_wrkd,payrate):
    reg_hrs = hrs_wrkd
    reg_pay = reg_hrs * payrate
    OT_hrs = 0
    OT_pay = 0
    return reg_hrs,reg_pay,OT_hrs,OT_pay

#This function should calculate the Overtime pay for the employee
#It accepts arguments from the get_info function as well

def calculate_OT_pay(hrs_wrkd,payrate):
    reg_hrs = hrs_wkrd - 40
    reg_pay = reg_hrs * payrate
    OT_hrs = hrs_wrkd - reg_hrs
    OT_pay = OT_hrs * (payrate * 1.5)
    return reg_hrs,reg_pay,OT_hrs,OT_pay

#This function decides which calculation to use, either OT or regular pay
#It also accepts srguments from get_info

def calc_employee(hrs_wrkd,payrate):
    if hrs_wrkd <= 40:
        calculate_reg_pay(hrs_wrkd,payrate)
    else:
        calculate_OT_pay(hrswrkd,payrate)

#This function should print the single employee information after it was calculated
#It gets its arguments from the calc_employee function

def print_employee(reg_pay,OT_pay,name):
    print(name,'earned $',format(reg_pay,'.2f'),' worth of regular pay and ',format(OT_pay,'.2f'),' in overtime this week.')

#This function is supposed to calculate the running total of the hours and pay for overtime and regular pay for the company
# It accepts its arguments from the calc_employee function also

def running_total(reg_hrs,reg_pay,OT_hrs,OT_pay,total_reg_hrs,total_reg_pay,total_OT_hrs,total_OT_pay):
    total_reg_hrs = total_reg_hrs + reg_hrs
    total_reg_pay = total_reg_pay + reg_pay
    total_OT_hrs = total_OT_hrs + OT_hrs
    total_OT_pay = total_OT_pay + OT_pay
#This function is supposed to print out the running total for the company, but I realized that it isnt in the proper position when called

def print_totals(total_reg_hrs,total_reg_pay,total_OT_hrs,total_OT_pay):
    print('The total regular hours worked was',total_reg_hours)
    print('The total regular pay was $',format(total_reg_pay,'.2f'))
    print('The total overtime hours worked was',total_OT_hours)
    print('The total overtime pay was $',format(total_OT_pay,'.2f'))

# So here I am defining the main loop that will activate everytime the user selects Yes
#It calls most of the other functions

def main_loop():
    get_info
    calc_employee
    print_employee
    running_total
#Here I am defining the main program where I put the loop control


def main():
    loop_control = input("Would you like to enter an employee's name, payrate and hours? y to do so")
    if loop_control == "y":
        main_loop
    else:
        print_totals(total_reg_hrs,total_reg_pay,total_OT_hrs,total_OT_pay)
   #Here we call the main function

main()

推荐答案

您需要调用您的函数，这只会引用函数对象：

You need to call your functions. This does nothing but reference the function object:

main_loop

添加（）功能：

Add () to call a function:

main_loop()

在您的 main_loop（）函数中相同：

Same in your main_loop() function:

def main_loop():
    get_info()
    calc_employee()
    print_employee()
    running_total()

不是那样，因为你的函数需要参数;你需要在函数调用中传入这些参数。 c $ c> get_info（）接受它忽略的参数;删除这些参数（）函数签名：

Not that that'll work, because your functions take parameters; you need to pass those in in a function call to work. get_info() takes parameters it then ignores; remove those parameters in the function signature:

def get_info():
    print('is this working?');
    name = input('What is the last name of the employee?');
    hrs_wrkd = float(input('How many hours did',name,' work last week?'));
    payrate = float(input('How much does',name,' get paid?'));
    return name,hrs_wrkd,payrate

接下来，您要指定返回值的; get_info（）会返回一些内容，但您从不指定任何内容：

Next you want to assign return values; get_info() returns a few things, but you never assign any of them:

name, hours_worked, payrate = get_info()

现在您可以将这些传递给其他函数调用：

Now you can pass these to other function calls:

calc_employee(hours_worked, payrate)

等。

您已经退出了一些修复程序，这超出了范围这个答案虽然。不要忘记在函数调用中也使用 return ！例如， calc_employee 不会返回任何内容，例如，它只是忽略它委托给它返回的功能。

You'll have quit a few more to fix, that is outside the scope of this answer though. Don't forget to use return on function calls too! calc_employee doesn't return anything, for example, it simply ignores what the functions it delegates to return, for example.
