Question

如果您能让我知道如何将html表转换为数据框，我将不胜感激。

import pandas as pd
df = pd.read_html('https://www.iasplus.com/en/resources/ifrs-topics/use-of-ifrs', header = None)

错误：

C:\Users\t\Anaconda3\python.exe C:/Users/t/Downloads/hyperopt12.py
Traceback (most recent call last):
  File "C:/Users/t/Downloads/hyperopt12.py", line 12, in <module>

谢谢。

您需要在页面上找到正确的表格才能阅读。 read_html返回数据框对象的列表。请参阅文档here。

import pandas as pd
tables = pd.read_html('https://www.iasplus.com/en/resources/ifrs-topics/use-of-ifrs', header = None)
df = tables[2]
df

如何将HTML表格读取为资料框（urllib.error.URLError：<urlopen error =“” unknown =“” url =“” type：=“” https =“”>）？
