python - 让 python 一次验证一个

Question

我有这个程序工作，但是当我验证它时，它需要在每个数字之后而不是末尾进行验证。我如何让它在每次输入数字后进行检查并仍然保留它们本身的功能。当我遇到各种错误后，它会立即返回一个数字。

def main():
    num1, num2, num3, num4, num5 = getinput()
    num1, num2, num3, num4, num5 = verify_num(num1, num2, num3, num4, num5)
    average_score,score = calc_average(num1, num2, num3, num4, num5)
    average_score = determine_grade(score)
    calprint(num1, num2, num3, num4, num5, score, average_score)

def getinput():
    num1 = int(input('Please enter your first test score: '))
    num2 = int(input('Please enter your second test score: '))
    num3 = int(input('Please enter your third test score: '))
    num4 = int(input('Please enter your fourth test score: '))
    num5 = int(input('Please enter your fifth test score: '))
    return num1, num2, num3, num4, num5

def verify_num(num1, num2, num3, num4, num5):
    while num1 < 0 or num1 > 100:
        print ('Error--- The number musy be at least 0 and not more than 100.')
        num1 = int(input('Please enter your first test score: '))
    while num2 < 0 or num2 > 100:
        print ('Error--- The number musy be at least 0 and not more than 100.')
        num2 = int(input('Please enter your second test score: '))
    while num3 < 0 or num3 > 100:
        print ('Error--- The number musy be at least 0 and not more than 100.')
        num3 = int(input('Please enter your third test score: '))
    while num4 < 0 or num4 > 100:
        print ('Error--- The number musy be at least 0 and not more than 100.')
        num4 = int(input('Please enter your fourth test score: '))
    while num5 < 0 or num5 > 100:
        print ('Error--- The number musy be at least 0 and not more than 100.')
        num5 = int(input('Please enter your fifth test score: '))
    return num1, num2, num3, num4, num5

def calc_average(num1, num2, num3, num4, num5):
    score = (num1 + num2 + num3 + num4 + num5)
    average_score = score / 5.0
    return score, average_score

def determine_grade(score):
    if score > 90:return '4.0'
    elif score > 80:return '3.0'
    elif score > 70:return '2.0'
    elif score > 60:return '1.0'
    return '0.0'

def calprint (num1, num2, num3, num4, num5, score, average_score):
    print
    print ("Score #1   ", format (num1))
    print ("Score #2   ", format (num2))
    print ("Score #3   ", format (num3))
    print ("Score #4   ", format (num4))
    print ("Score #5   ", format (num5))
    print ()
    print ("Average score",format (score))
    print ("Average grade",format (average_score))


main()

有一个函数要求并读取一个数字，直到输入有效数字，然后返回该有效数字。为 5 个输入中的每一个输入调用它。 (您可能想传递此函数正在获取的数字。)
