无法使用pynput python记录字母数字字符

Question

如何在 pynput 中跟踪字母数字字符和非特殊字符（空格键，删除，制表符等）。我使用以下代码。此代码仅输出特殊字符，而不输出通过键盘输入的任何其他字符。

from pynput.keyboard import Key, Listener

#defining function to print when key is pressed
def on_press(key):
    print('{0} pressed'.format(key))

#defining function to print when key is released
def on_release(key):
    print('{0} release'.format(key))
    if key == Key.esc:
        # Stop listener
        return False

# Collect events until released
with Listener(on_press=on_press, on_release=on_release) as listener:
    listener.join()
