我希望我的 python 程序在不使用函数的情况下循环

Question

我正在开发一款井字游戏。我已经完成了，但是如果用户要求它，我希望它再次循环。问题是当我把它放在一个主要功能下并缩进它时。一些变量不再定义，它不起作用！当它不在 main() 函数下时，它们会这样做。这些错误不会发生。有谁知道如何在不使用函数的情况下循环程序，或者帮助修复我的代码。例如：

def main():
    #My code here
#Ouput:
  File "CandT.py", line 205, in <module>
  main()
  File "CandT.py", line 203, in main
  run()
  File "CandT.py", line 188, in run
  runX()
  File "CandT.py", line 163, in runX
  askX()
  File "CandT.py", line 59, in askX
  check_stringX(x = s1)
  NameError: name 's1' is not defined

像这样创建一个while 循环。

def run()
    clear()
    #check_win() should return true if there is a winner or false if not
    while(check_win()==False): #if there is nobody win, continue this loop
        if turn == 0: # X's move
            runX()
            turn = 1 # the next turn will be O's
        elif turn == 1: # O's move
            runO()
            turn = 0 # the next turn will be O's

    #here after the loop, we check for the winner
    if(turn == 0):
        winner = O #because the last move is O's
    else:
        winner = X

def clear():
#reset all variables here

if __name__ == "__main__": #maybe you miss this line 
    while(True):
        play_again = int(input("play again? 1: OK, 0: No"))
        if play_again == 1:
            run()
        else:
            break
