pandas read_html - 没有找到表

Question

我试图查看是否可以从 WU.com 读取数据表，但由于未找到表而收到类型错误。（这里也是网络抓取的第一次）还有另一个人在这里提出了与 WU 数据表非常相似的 stackoverflow 问题，但解决方案对我来说有点复杂。

import pandas as pd

df_list = pd.read_html('https://www.wunderground.com/history/daily/us/wi/milwaukee/KMKE/date/2013-6-26')

print(df_list)

在密尔沃基的历史数据网页上daily observations，这是我尝试检索到 Pandas 中的 数据表 ( )：

任何提示都有帮助，谢谢。

该页面是动态的，这意味着您需要首先渲染页面。因此，您需要使用 Selenium 之类的东西来渲染页面，然后您可以使用 pandas 拉取表格.read_html()：

from selenium import webdriver
import pandas as pd


driver = webdriver.Chrome('C:/chromedriver_win32/chromedriver.exe')
driver.get("https://www.wunderground.com/history/daily/us/wi/milwaukee/KMKE/date/2013-6-26")

html = driver.page_source

tables = pd.read_html(html)
data = tables[1]

driver.close()

输出：

print (data)
