我有一個(gè)等待按鍵并將它們記錄在控制臺(tái)中的腳本：from pynput.keyboard import Key, Listenerdef on_press(key): print('{0} pressed'.format( key))def on_release(key): print('{0} release'.format( key)) if key == Key.esc: # Stop listener return False# Collect events until releasedwith Listener( on_press=on_press, on_release=on_release) as listener: listener.join()系統(tǒng)本身可以工作，但是，當(dāng)按住某個(gè)鍵時(shí)，它會(huì)產(chǎn)生以下結(jié)果：Key.space pressedKey.space pressedKey.space pressedKey.space pressedKey.space pressedKey.space pressedKey.space pressedKey.space pressedKey.space pressed如何使線程暫停，直到釋放鍵？

我們可以使用一個(gè)集合來檢查當(dāng)前正在按下哪個(gè)鍵。
pressing_keys_set = set()
def on_press(key):
if key not in pressing_keys_set:
print('{0} pressed'.format(key))
pressing_keys_set.add(key)
def on_release(key):
print('{0} release'.format(key))
pressing_keys_set.remove(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()

此代碼必須幫助您
from pynput.keyboard import Key, Listener
is_released=False
def on_press(key):
global is_released
if is_released:
print('{0} pressed'.format(key))
is_released=False
def on_release(key):
global is_released
print('{0} release'.format( key))
is_released=True
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()
