翻译The goal of datasource is to abstract some of the file system operations when dealing with data files so the researcher doesn't have to know all the low-level details. Through datasource, a researcher can obtain and use a file with one function call, regardless of location of the file. DataSource is meant to augment standard python libraries, not replace them. It should work seamlessly with standard file IO operations and the os module. DataSource files can originate locally or remotely: - local files : '/home/guido/src/local/data.txt' - URLs (http, ftp, ...) : 'http://www.scipy.org/not/real/data.txt' DataSource files can also be compressed or uncompressed. Currently only gzip, bz2 and xz are supported.

DataSource的目标是在处理数据文件时抽象一些文件系统操作，以便研究人员不需要了解所有低级细节。通过使用DataSource，研究人员可以通过一个函数调用获取和使用文件，而不管文件的位置。

DataSource旨在增强标准的Python库，而不是取代它们。它应该与标准的文件IO操作和os模块无缝配合工作。

DataSource文件可以是本地的，也可以是远程的：

- 本地文件：'/home/guido/src/local/data.txt'
- URL（http、ftp等）：'http://www.scipy.org/not/real/data.txt'

DataSource文件还可以是压缩或非压缩的。目前仅支持gzip、bz2和xz格式。
