如何查看使用Pynput python 3.7按下的字符？

Question

您如何查看在Pynpuy中按下了哪个按钮。

from pynput.keyboard import Key, Listener

def a(key):
    print('{0} pressed'.format(
        key))
    if key == 'a':
        print('ape')

with Listener(on_press = a) as listener:
    listener.join()

看不到工作。

Answer 1

您所拥有的一切正常：

from pynput.keyboard import Listener

def a(key):
    print(f"{key}, was pressed")

with Listener(on_press=a) as listener:
    listener.join()

输出：

'q', was pressed
'w', was pressed
'e', was pressed
'r', was pressed
't', was pressed
'y', was pressed

虽然您不一定需要Key导入或if语句。

如果您正在寻找特定的按键，请按如下所示：

import keyboard

while True:
    if keyboard.read_key() == "a":
        print("You pressed a")
        break

将工作

也：

if str(key) == "'a'":
    print("a pressed")

将返回：

'a', was pressed
a pressed

Answer 2

您可以使用pygame这有点复杂。如果您想通过按下按钮来触发命令，这是最有用的。它还可以检测F键，命令键等！

这是操作方法：

import pygame
pygame.init()
while True:
 for event in pygame.event.get():
  if event.type==pygame.KEYDOWN:
   if event.key==pygame.K_SPACE:
    print("Space is pressed!")
