python键盘监听及模拟键盘输入

import sys,os
from pynput.keyboard import Controller,Key,Listener
import datetime

def on_press(key):
    try:
        nowTime = datetime.datetime.now().strftime('%H:%M:%S')
        print("正在按压:", format(key.char),"时间:",nowTime)
    except AttributeError:
        print("正在按压:", format(key))


# 监听释放
def on_release(key):
    nowTime = datetime.datetime.now().strftime('%H:%M:%S')
    print("已经释放:", format(key))

    if key == Key.esc:
        # 停止监听
        return False


# 开始监听
def start_listen():
    with Listener(on_press=on_press, on_release=on_release) as listener:
        listener.join()


if __name__ == '__main__':
    # 实例化键盘
    # kb = Controller()

    # # 使用键盘输入一个字母
    # kb.press('a')
    # kb.release('a')
    #
    # # 使用键盘输入字符串,注意当前键盘调成英文
    # kb.type("hello world")
    #
    # # 使用Key.xxx输入
    # kb.press(Key.space)

    # 开始监听,按esc退出监听
    print("hello")
    start_listen()
