我怎么會問他們是否要重新計算？

Question

到目前為止，這是我所擁有的，但我似乎無法讓代碼起作用，讓我在計算結束時詢問他們是否想再次進行計算。

#_function definitions_________________________________________________________________________________________________

def validate_pay_rate(pay_rate):
    while pay_rate < 7.5 or pay_rate > 18.25:
        print ("\nERROR: You entered an invalid pay rate...")
        pay_rate = float(input("Enter employee's pay rate: $"))
    else:
        return pay_rate

def validate_hours_worked(hours_worked):
    while hours_worked <= 0 or hours_worked > 40:
        print ("\nERROR: You entered an invalid amount of work hours...")
        hours_worked = float(input("Enter hours worked: "))
    else:
        return hours_worked

def calculate_gross_pay(pay_rate, hours_worked):
    print("Gross Pay = $" + "%.2f" % float(pay_rate * hours_worked))



#_main_________________________________________________________________________________________________________________
pay_rate = float(input("Enter employee's pay rate: $"))
validate_pay_rate(pay_rate)
hours_worked = float(input("Enter hours worked: "))
validate_hours_worked(hours_worked)
calculate_gross_pay(pay_rate, hours_worked)

Answer 1

在主塊周圍放置一個循環。 像這樣的事情會起作用。 您當然應該為輸入做一些更好的事情，但那是最小版本。

#_main_________________________________________________________________________________________________________________
calculated = False
while not calculated or input("Redoo or something else (type y/n)") == "y":
    pay_rate = float(input("Enter employee's pay rate: $"))
    validate_pay_rate(pay_rate)
    hours_worked = float(input("Enter hours worked: "))
    validate_hours_worked(hours_worked)
    calculate_gross_pay(pay_rate, hours_worked)
    calculated = True

Answer 2

如果我理解正確，這就是你想要的。

#main_____________________________________________________________________________
while True:
    pay_rate = float(input("Enter employee's pay rate: $"))
    validate_pay_rate(pay_rate)
    hours_worked = float(input("Enter hours worked: "))
    validate_hours_worked(hours_worked)
    calculate_gross_pay(pay_rate, hours_worked)
    continue_ = input("Do you want to do this again? Y/N: ")
    if continue_ == "n" or continue_ == "N":
        break
    else:
        print() # Just to get a space between each input
