＃使用@H_502_1@pynput模块：（ 最佳）
您可以使用以下代码：
@H_502_1@from pynput import keyboard import time def on_key_release(key): #what to do on key-release time_taken = round(time.time() - t, 2) #rounding the long decimal float print("The key",key," is pressed for",time_taken,'seconds') return False #stop detecting more key-releases def on_key_press(key): #what to do on key-press return False #stop detecting more key-presses with keyboard.Listener(on_press = on_key_press) as press_listener: #setting code for listening key-press press_listener.join() t = time.time() #reading time in sec with keyboard.Listener(on_release = on_key_release) as release_listener: #setting code for listening key-release release_listener.join()
＃使用@H_502_1@pygame：（ 好）
@H_502_1@import time import pygame import os os.environ["SDL_VIDEO_CENTERED"] = "1" screen = pygame.display.set_mode((600, 600)) pygame.display.set_caption("Time") clock = pygame.time.Clock() pygame.init() clock = pygame.time.Clock() running = True while running: for event in pygame.event.get(): if event.type == pygame.QUIT: running = False pygame.quit() break if event.type == pygame.KEYDOWN: # detect key 'a' if event.key == pygame.K_a: # key 'a' t = time.time() if event.type == pygame.KEYUP: if event.key == pygame.K_a: # key 'a' t = time.time() - t; t = str(t); t = t[:5] print("You pressed key 'a' for",t,'seconds') screen.fill((255, 255, 255)) pygame.display.update() clock.tick(40)
它只会检测您将在代码中编写的键。
使用@H_502_1@pip install pynput安装@H_502_1@pynput。 使用@H_502_1@pip install pygame安装@H_502_1@pygame。
