python使用playwright

使用Playwright可以在Python脚本中进行自动化程序的编写。首先，需要通过pip命令安装Playwright。然后可以使用import语句导入Playwright库。根据个人喜好，可以选择启动chromium、firefox或webkit浏览器。以下是一个简单的示例代码，实现了控制chromium浏览器打开百度首页，并获取页面源码的title属性值并打印在Python控制台上：

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch()
    page = browser.new_page()
    page.goto("https://www.baidu.com/")
    print(page.title())
    browser.close()

请注意，默认情况下，Playwright以无头模式运行浏览器，所以并不会弹出浏览器界面。如果希望查看浏览器界面，可以在启动浏览器时传递`headless=False`参数。以下是示例代码：

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch(headless=False)
    page = browser.new_page()
    page.goto("https://www.baidu.com/")
    print(page.title())
    browser.close()
