python控制键盘按键_如何通过Python生成键盘按键事件来控制PP的表示？

您可以为Python使用Quartz库，例如#!/usr/bin/python

# Script simulating keyboard events in macOS.

# See: https://stackoverflow.com/q/13564851/55075

import sys

import time

from Quartz.CoreGraphics import CGEventCreateKeyboardEvent

from Quartz.CoreGraphics import CGEventPost

from Quartz.CoreGraphics import kCGHIDEventTap

#from Quartz.CoreGraphics import CFRelease # Python releases things automatically.

下面是使用上述类的演示代码：# DEMO

if __name__ == '__main__':

keyboard = Keyboard()

if sys.platform == "darwin":

keyboard.Type('Hello World!')

elif sys.platform == "win32":

print("Error: Platform not supported!")

它将模拟在当前窗口上键入Hello World!文本。

上面的代码可以作为shell脚本运行。检查指向^{} file的链接。
