Python通过keyboard库实现模拟和监听键盘

import keyboard
 
def log_keystroke(event):
    print(f"Key {event.name} {'被按下' if event.event_type == 'down' else '被释放'}")
 
keyboard.hook(log_keystroke)
 
# 使用esc键来停止监听
keyboard.wait("esc")

import keyboard
import time
 
# 记录按键
keyboard.start_recording()
 
# 设置记录10秒的键盘输入
time.sleep(10)
 
events = keyboard.stop_recording()
 
# 回放记录的按键
keyboard.play(events)
监听特定键的按下和释放
import keyboard
 
def on_press_reaction(event):
    if event.name == "b":
        print("你为什么要按b？")
 
 
keyboard.on_press(on_press_reaction)
 
keyboard.wait("esc")

import keyboard
 
def print_message():
    print("你为什么要召唤我？")
 
# 设置热键，例如alt+b
keyboard.add_hotkey("alt+b", print_message)
 
keyboard.wait("esc")

import keyboard
import datetime
 
 
def write_timestamp():
    current_time = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
    
    keyboard.write(current_time)
 
keyboard.add_hotkey("ctrl+b", write_timestamp)
keyboard.wait("esc")

    current_time = datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
    
    info = f"作者：{name}\n联系方式：{mail}\n创建时间：{current_time}"
    
    keyboard.write(info)
 
keyboard.add_hotkey("ctrl+b", lambda: write_info("sagegrass", "sagegrass@outlook.com"))
keyboard.wait("esc")
