如何通过playwright 控制它 python

您可以使用 Python Playwright 库来控制 Playwright。您需要安装 Playwright 和 Python Playwright，并编写 Python 代码来控制它。以下是一些示例代码：

1. 安装 Playwright 和 Python Playwright:

npm i playwright
pip install playwright

2. 编写 Python 代码：

from playwright.sync_api import Playwright, async_playwright

async def run(playwright: Playwright) -> None:
    # 启动 Chromium 浏览器
    browser = await playwright.chromium.launch()
    # 创建一个新的页面
    page = await browser.new_page()
    # 跳转到百度
    await page.goto('https://www.baidu.com/')
    # 获取搜索框对象
    search_input = await page.query_selector('#kw')
    # 在搜索框中输入关键字
    await search_input.type('Python')
    # 获取搜索按钮对象
    search_button = await page.query_selector('#su')
    # 点击搜索按钮
    await search_button.click()
    # 等待搜索结果加载完毕
    await page.wait_for_selector('#content_left')
    # 关闭浏览器
    await browser.close()

with async_playwright() as playwright:
    # 启动 run 函数
    playwright.run(run)

这段代码将启动 Chromium 浏览器，然后打开百度，输入关键字并点击搜索按钮，等待结果加载完毕后关闭浏览器。您可以根据需要修改此代码来控制 Playwright。
