Python 如何使用print（chr（27）&“x2B”[2J”）？当我使用print（）函数时，input（）函数工作不正常。谢谢

我正在用Python制作HangMan游戏。它几乎已经准备好了，但当我每次在循环运行时使用print（chr（27）+“[2J”）清除控制台时，它会清除，但我的guess=input（“猜字母”）不起作用。当我把它评论出来时，它又完美地工作了。我不明白问题是什么。我搜索了我的问题的答案，但我找不到。如果有人解释一下这个打印（chr（27）+“[2J”）是如何工作的，我将不胜感激。下面是我的代码：

   #columns  0   1   2   3   4   5   6   7   8   9  10  11                                  
gallowList = [                                                   #rows
          [" "," "," "," "," "," "," "," "," ","|"," "," \n"],   #0
          [" "," "," "," "," "," "," "," "," ","|"," "," \n"],   #1
          [" "," "," "," "," "," "," "," "," ","|"," "," \n"],   #2
          [" "," "," "," "," "," "," "," "," ","|"," "," \n"],   #3
          [" "," "," "," "," "," "," "," "," ","|"," "," \n"], #4
                                                            ]          

def gallow(listVar):
    print( "    _____   " + "\n" + 
           "   |     |  "          )
   
    for row in listVar:
        for col in row:
             
            print(col, end = "")
        
    print( " ________|_ " + "\n" + 
           "|          |"        )    




word = input("Think of a word: ")
while word.isspace() or len(word) == 0:
    word = input("Think of a valid word: ")

如果这是Windows，那么

[2J

序列早就有问题了（尽管它可能已经被修复）。请尝试

[H[J

。另外，我想您可以在字符串中编码

ESC

，而不是使用

chr（）

：尝试

“\x1b[H\x1b[J”

。

while

循环之所以运行，是因为您处于

while

循环中，并且从未告诉它停止。您需要在函数中获取

while

，这样您就可以中断该循环，然后返回该循环。谢谢您的回答。
