Python脚本不工作def

Question

The code below keeps skipping the "TryAgainQuestion()" function:::: I Realy need some help!!! It is becoming annoying

    import time
    ranname = "0"

def AskForName():
    ranname = "1"
    name = input("Please enter your name: ")
    print("--------------------")
    print("  .:: ",name," ::.")
    print("--------------------")
    print("     ")
    time.sleep(2)
    Start()

def TryAgainQuestion():
    tryagain = input("Do you want to try again? (Y or N): ")
    if (tryagain == "y" or "Y"):
        AskForName()

    else:
        time.sleep(1)
        print("Made By: Daniel Parker")

def Start():
    if (ranname == "1"):
        TryAgainQuestion()

    if (ranname == "0"):
        AskForName()
Start()

Thanks, Dan

Answer 1

It's a scope problem : the ranmame at the second line is not the same as the one in the AskForName function. You need to add global ranname at the beginning of the function to update properly.

import time
ranname = "0"

def AskForName():
    global ranname
    ranname = "1"

Answer 2

As suggested and said by @georgesl it's scope problem (namespace)

Please read this guide, i'm attaching a working code by a class:

import time

class myClass():

    def __init__(self):
        self.ranname = "0"

    def AskForName(self):
        self.ranname = "1"
        name = raw_input("Please enter your name: ")
        print("--------------------")
        print("  .:: ", name, " ::.")
        print("--------------------")
        print("     ")
        time.sleep(2)
        self.Start()

    def TryAgainQuestion(self):
        tryagain = raw_input("Do you want to try again? (Y or N): ")
        if (tryagain == "y"):
            self.AskForName()

        else:
            time.sleep(1)
            print("Made By: Daniel Parker")

    def Start(self):
        if self.ranname == "1":
            self.TryAgainQuestion()

        if self.ranname == "0":
            self.AskForName()

def main():

    myclass = myClass()
    myclass.Start()

   #end of main

if __name__ == "__main__":
    main()
