读取CSV文件: 这里的'file.csv'是你要读取的CSV文件的路径。 分隔数据: 分隔数据: 这里的'column_name'是你要分隔的列名,'separator'是你要使用的分隔符。通过str.split()函数可以将指定列中的数据按照指定的分隔符进行分隔,并使用expand=True参数将分隔后的数据展开为多列。
(可选)设置to_csv方法中的其他参数: to_csv方法还提供了许多其他参数,用于自定义CSV文件的格式。例如,可以指定分隔符(sep参数)、编码(encoding参数)等。 python df.to_csv('data_with_custom_separator.txt', sep=';', index=False, encoding='utf-8') 在上述代码中,将分隔符设置为分号(;),并将编码设...
