我的程序关于寻找因子的问题 [英] Problem with my program about finding factors

问题描述

这是我旧问题的延续该程序在没有

This was a continuation to my older question The program was working fine without the

虽然为真:主要的()if input("Try Again? (Yes/No)").strip().upper() == 'No':打破

while True: main() if input("Try Again? (Yes/No)").strip().upper() == 'No': break

但是当我添加它时，问题出现了

but when i added it, the problem rose

我试图通过询问用户一个数字来启动程序它显示了一个因素，然后我循环它并询问用户他是否想要另一个数字，如果用户想要重复它会重复

I was trying to make the program start by asking the user a number and it shows a factor then i loop it and ask the user if he wants another number and it repeats if the user wants to repeat it

def main():

 def print_factors(x):
    print("The factors of",x,"are:")
    for i in range(1, x + 1):
    if x % i == 0:
        print(i)


try:
    num = int(input("Enter a number: "))
    print_factors(num)
except ValueError:
    print("Sorry, I didn't understand that.");

while True:
    main()
    if input("Try Again? (Yes/No)").strip().upper() == 'No':
    break


line 12, in <module>
    print_factors(num)
NameError: name 'print_factors' is not defined

当程序运行时这是最终结果

when the program is ran this was the end result

推荐答案

您在 main() 内部定义了 print_factors，这意味着它不是全局作用域可用的函数

You defined print_factors inside of main(), meaning it's not a function available to the global scope

给 main() 一个正文，并取消缩进 print_factors() 它应该可以解决您的问题

Give main() a body, and unindent print_factors() and it should resolve your issues
