我应该使用哪一个:os.sep或os.path.sep? [英] which one should I use: os.sep or os.path.sep?

问题描述

它们是相同的，但是我应该使用哪一个?

They are same, but which one should I use?

http://docs.python.org/library/os.html :

os.sep

操作系统用来分隔路径名组件的字符.对于POSIX，这是"/"；对于Windows，这是"\".请注意，仅知道这一点不足以解析或连接路径名-使用os.path.split()和os.path.join()-但这有时很有用.也可以通过os.path获得.

The character used by the operating system to separate pathname components. This is '/' for POSIX and '\' for Windows. Note that knowing this is not sufficient to be able to parse or concatenate pathnames — use os.path.split() and os.path.join() — but it is occasionally useful. Also available via os.path.

推荐答案

我将使用os.path.sep清楚地表明它是路径分隔符……但是一致性更重要，因此，如果已经使用了它，请使用那.否则，请选择一个并一直使用.

I'd use os.path.sep to make it very clear that it's the path separator… But consistency is more important, so if one is already being used, use that. Otherwise, pick one and use it all the time.

编辑:为了确保您没有重新发明轮子，尽管path模块已经具有join，split，dirname和basename功能…因此，您几乎不需要使用path.sep:

Edit: Just to make sure you're not reinventing the wheel, though, the path module already has join, split, dirname, and basename functions… So you should rarely need to use path.sep:

>>> os.path.join("foo", "bar", "baz")
'foo/bar/baz'
>>> os.path.split(_)
('foo/bar', 'baz')
