本地文件可以是:file://localhost/path/to/table.csv。 如果要传入路径对象,pandas接受pathlib.Path 或py._path.local.LocalPath。 通过类似文件的对象,我们使用read()方法引用对象, 例如文件处理程序(例如,通过内置的open函数)或StringIO。 sep:str,默认',' 分隔符使用。如果sep

In Pandas, you can save a DataFrame to a CSV file using the df.to_csv('your_file_name.csv', index=False) method, where df is your DataFrame and index=False prevents an index column from being added.
