python playwright选取class为python playwright的ul标签

要使用Python Playwright选择class为"python playwright"的ul标签，可以按照以下步骤进行操作：

1. 导入Playwright库：

from playwright.sync_api import sync_playwright

2. 启动Playwright并创建一个浏览器实例：

with sync_playwright() as playwright:
    browser = playwright.chromium.launch()
    page = browser.new_page()

3. 打开目标网页：

page.goto("https://example.com")

4. 使用CSS选择器选择目标元素：

ul_element = page.query_selector('ul.python.playwright')

这里使用了CSS选择器，其中`ul.python.playwright`表示选择class为"python playwright"的ul标签。

5. 获取元素的文本内容：

ul_text = ul_element.inner_text()
print(ul_text)

6. 关闭浏览器实例：

browser.close()
