如何获取PyWin32中提供密钥的密钥名称？

我在读PyWin32 docs，出于某种原因，GetKeyNameText function不存在。不可能使用GetKeyState或GetKeyboardState返回名称，因为很显然，它们只返回只有的状态。那么，为什么GetKeyNameText不在那里，我怎样才能得到一个键的名字给它的键码（从0到256）？如何获取PyWin32中提供密钥的密钥名称？

例子：

import win32api 

if __name__ == "__main__": 

    while True: 
     for key in range(256): 
      if int(win32api.GetKeyState(key)): 
       print(win32api.GetKeyNameText(key)) # Not available in PyWin32.

输出：

Traceback (most recent call last): 
    File "main.py", line 32, in <module> 
    print(win32api.GetKeyNameText(key)) # Not available in Python. 
AttributeError: 'module' object has no attribute 'GetKeyNameText' 
Press any key to continue . . .

对于按键，你最有可能需要创建VK_CODE到键的字典，虚拟键代码存在here，例 -

VK_CODE = {8: 'backspace', 
9: 'tab', 
12: 'clear', 
13: 'enter', 
16: 'shift', 
17: 'ctrl', 
18: 'alt', 
19: 'pause', 
20: 'caps_lock', 
27: 'esc', 
32: 'spacebar', 
33: 'page_up', 
34: 'page_down', 
35: 'end',

248: 'exsel_key', 
250: 'play_key', 
251: 'zoom_key', 
254: 'clear_key'}

另外，您应该检查int(win32api.GetKeyState(key)) agai如果密钥被切换，则可以是1。
