如何查看pynput python 3.7中按下的字符？

您如何看到pynput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()

看不见工作

from pynput.keyboard import Listener
def a(key):
    print(f"{key}, was pressed")
    if key.char == "a":
        print("foo")


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

输出：

q'q', was pressed
w'w', was pressed
a'a', was pressed
foo
s's', was pressed

但是，如果您按下caps lock（大写锁定），这将导致问题，例如，我将在try except块中放置：

try:
    if key.char == 'a':
        print("foo")
except AttributeError:
    pass
