Python 靓汤：提取天气信息：表格-->；Excel文件

我想从这个表中提取数据

天气历史表

我需要什么

• 提取
  \
  中所有
  的所有内容
• 从python生成包含整个数据的Excel文件

我不需要的

• 数字旁边的所有单位（即：22°C） （我不想要
  中的
  ）
  

  33.8°C

• 排除
  \
  和

有人能告诉我如何在Excel文件中提取这些数据吗

您好，比尔，谢谢您的回复，但我有以下错误：文件“”，第2行[.text.split（）[0]代表行中的_。选择（'td'）]^SyntaxError:无效语法更多（我刚刚更新了html代码）我不需要，为了查看结果，我添加了以下代码数据[]对于测试中的行。选择（“#history_table>tbody>tr”）：data.append=[.text.split（）[0]表示行中的行。选择（'td'）]表示行中的行打印（数据）

[.text.split（）[0]表示行中的行。选择（'td'）]

：如果这是代码的精确副本，则它缺少开头附近的下划线（'uu'）。请参考我答案中的代码。

用于测试中的行。选择（“#history#u table>tbody>tr”）：[#text.split（）[0]用于行中的行。选择（'td'）]文件“”，第2行[#text.split（）[0]用于行中的行。选择（'td'）]^SyntaxError:无效语法

这是正确的代码。即使代码有效，我也不知道如何列出所有的

，除了

和``在

中。最后看一下html
