Python 从网站中提取数据

我正试图从网站中提取数据

该表有一个span标记，它扰乱了数据提取，表值与span标记连接，我想在单独的单元格中提取单元格内容和span标记，如有帮助，将不胜感激

这是密码

import pandas as pd

url = "https://www.sqimway.com/lte_band.php"

lte_band = pd.read_html(url)

lte_band[0]

---

如果您有pandas 0.24+，则可以使用并映射出每个列名的唯一值

# Set a new DataFrame variable.
df = lte_band[0]

# Note: We will have to sort on the tuple index to retain order.
df.columns = list(map(lambda q: " ".join(sorted(set(q), key = q.index)), df.columns.to_flat_index()))

df.列的输出

：

Index(['Band', 'Name', 'Mode', 'Downlink (MHz) Low Earfcn',
       'Downlink (MHz) Middle Earfcn', 'Downlink (MHz) High Earfcn',
       'BandwidthDL/UL (MHz)', 'Uplink (MHz) Low Earfcn',
       'Uplink (MHz) Middle Earfcn', 'Uplink (MHz) High Earfcn',
       'Duplex spacing(MHz)', 'Geographicalarea', '3GPPrelease',
       'Channel bandwidth (MHz) 1.4', 'Channel bandwidth (MHz) 3',
       'Channel bandwidth (MHz) 5', 'Channel bandwidth (MHz) 10',
       'Channel bandwidth (MHz) 15', 'Channel bandwidth (MHz) 20'],
      dtype='object')

格式：
