从入门到精通详解Python键盘鼠标自动化库

pip install pyautogui

import pyautogui
import time

# 设置暂停时间，给操作留出缓冲
pyautogui.PAUSE = 1

# 获取屏幕尺寸
screen_width, screen_height = pyautogui.size()
print(f"屏幕尺寸: {screen_width}x{screen_height}")

# 移动鼠标到指定位置
pyautogui.moveTo(100, 100, duration=1)  # 持续1秒移动到(100,100)

# 相对移动
pyautogui.moveRel(50, 50, duration=0.5)  # 相对当前位置移动50,50

# 鼠标点击
pyautogui.click(200, 200)  # 在(200,200)位置单击
pyautogui.doubleClick(300, 300)  # 双击
pyautogui.rightClick(400, 400)  # 右键单击

# 鼠标拖拽
pyautogui.dragTo(500, 500, duration=1)  # 拖拽到指定位置
pyautogui.dragRel(100, 0, duration=0.5)  # 相对拖拽

# 滚动鼠标
pyautogui.scroll(500)  # 向上滚动500个单位
pyautogui.scroll(-500)  # 向下滚动500个单位

# 输入文本
pyautogui.typewrite('Hello World!', interval=0.1)  # 每个字符间隔0.1秒

# 按键操作
pyautogui.press('enter')  # 按回车键
pyautogui.press(['ctrl', 'a'])  # 组合键Ctrl+A

# 热键操作
pyautogui.hotkey('ctrl', 'c')  # Ctrl+C复制
pyautogui.hotkey('ctrl', 'v')  # Ctrl+V粘贴

# 按键事件
pyautogui.keyDown('shift')  # 按下Shift
pyautogui.typewrite('hello')  # 输入大写HELLO
pyautogui.keyUp('shift')  # 释放Shift

# 启用fail-safe模式（默认开启）
pyautogui.FAILSAFE = True

# 当鼠标移动到屏幕左上角时会触发FailSafeException
# 这可以防止程序失控

# PyAutoGUI目前只支持主显示器
# 如果需要支持多显示器，可以考虑使用其他库
# 或者使用pygetwindow等库来管理窗口

# 在某些系统上需要管理员权限
# macOS需要在系统偏好设置中允许辅助功能
# Linux可能需要安装额外的依赖
