python - 使用 pyppeteer 创建 for 循环的理想方法

Question

我用 python 结合 pyppeteer 编写了一个脚本，用于从网页上抓取不同咖啡馆的名称及其电话号码。虽然我下面尝试的方法达到了目的，但脚本看起来确实很困惑。使用 pyppeteer 库创建 for 循环的理想方法是什么？

到目前为止我已经写过:

import asyncio
from pyppeteer import launch

url = "https://www.yellowpages.com/search?search_terms=coffee&geo_location_terms=Los%20Angeles%2C%20CA"

async def get_names(link):
    wb = await launch(headless=True)
    page = await wb.newPage()
    await page.goto(link)

    containers = await page.querySelectorAll('div.v-card')
    for container in containers:
      name = await container.querySelector('.business-name span')
      phone = await container.querySelector('.phones')
      post = await page.evaluate('(element) => element.textContent', name)
      postAno = await page.evaluate('(element) => element.textContent', phone)
      print(f'{post}--{postAno}')

    await wb.close()

asyncio.get_event_loop().run_until_complete(get_names(url))

我会这样做:

import asyncio
from pyppeteer import launch

url = "https://www.yellowpages.com/search?search_terms=coffee&geo_location_terms=Los%20Angeles%2C%20CA"

async def get_names(link):
    wb = await launch()
    page = await wb.newPage()
    await page.goto(link)

    containers = await page.querySelectorAll('div.v-card')
    for container in containers:
        name = await container.querySelectorEval('.business-name span','e => e.innerText')
        phone = await container.querySelectorEval('.phones','e => e.innerText')
        print(name,phone)

asyncio.get_event_loop().run_until_complete(get_names(url))
