python-3.x - 如何使用 python 从 web 表中获取数据？

Question

我在尝试从此 Web 表中获取数据时遇到问题。我想知道是否有人可以阐明我的情况，谢谢！

HTML：

Answer 1

您想使用pandas.read_html()以将 HTML 表收集到pandasDataFrame 中。

用法：

>>> import pandas as pd
>>> pd.read_html(io)

来自文档的位置：

io : str 或类似文件
的URL、类似文件的对象或包含 HTML 的原始字符串。

例如，查看这个 Wikipedia URL：

In [0]: url = "https://en.wikipedia.org/wiki/List_of_Olympic_records_in_swimming"

In [1]: pd.read_html(url)[0]
