Pynput 键盘

问题描述

from pynput.keyboard import Key,Controller

keyboard = Controller()

s_key = input(str(" What leter do you want : "))

keyboard.press(s_key)
keyboard.release(s_key)

当我运行它时,它给了我一个错误,但是当我用 s_key 替换 Key.cmd(对于 Windows 键)它可以工作,但是如果我在它要求的地方输入 Key.cmd给我一个错误。我认为这是因为假设我输入了 key.cmd,它要求它将它用引号括起来,所以它看起来像这样:

keyboard.press("Key.cmd")
keyboard.release("Key.cmd")

我看过它,我得出的结论是,当你有一个这样的变量时,它会用引号将它包装起来,我认为 pynput.keyboard 不会在引号中注册特殊键:

keyboard.press(Key.cmd)
keyboard.release(Key.cmd)

解决方法

试试这个:

from pynput.keyboard import Key,Controller

keyboard = Controller()

try:
    s_key = getattr(Key,input("What letter do you want : ")) # get the key
except AttributeError:
    print("no such key %s " % s_key) # if the key is not valid,notify the user about it
else: # if key is valid
    keyboard.press(s_key)
    keyboard.release(s_key)

您必须输入 cmd 而不是 Key.cmd,因为如果您输入 Key.cmd,此代码会尝试使用 Key.Key.cmd,当然,它不会工作!
