我知道这是很多代码，但我不知道什么是重要的问题。 我不知道插入第一个​​后程序停止的原因;它不会重复以后

你必须在你的代码循环继续轮流。

这里是你的代码的第一个通过逻辑：

User_Turn = 1 
... 
if User_Turn == 21: # it's not 
    ... 
else: 
    if User_Turn % 2== 20: # it's not...actually can only be 0 or 1 never 20. 
    ... 
    else: 
     for turn in range(1): 
      ... # do all this stuff exactly once.
