df.drop('column_name', axis=1, inplace=True) ``` 以上代码将会删除DataFrame中名为'column_name'的列。 2.删除DataFrame的多列: ```python df.drop(['column_name1', 'column_name2'], axis=1, inplace=True) ``` 以上代码将会删除DataFrame中名为'column_name1'和'column_name2'的两列。 3....
df.drop(labels=['column1', 'column2'], axis=1, inplace=True) ``` 这样就可以删除DataFrame中的'column1'和'column2'两列数据。 3. 深入理解 除了基本的删除操作之外,drop()函数还可以帮助我们处理更复杂的情况。我们可以通过level参数来删除多层索引的行或列,通过index和columns参数来删除特定索引或标签...
