os.path.basename适用于URL，为什么? [英] os.path.basename works with URLs, why?

问题描述

>>> os.path.basename('http://example.com/file.txt')
'file.txt'

..并且我认为os.path.*仅适用于本地路径，而不适用于URL?请注意，上面的示例也是在Windows上运行的，结果相似.

.. and I thought os.path.* work only on local paths and not URLs? Note that the above example was run on Windows too .. with similar result.

推荐答案

在实践中，os.path的许多功能仅仅是字符串操作功能(对于路径操作而言， happen 特别方便)- -并且由于它是无害的，并且有时会派上用场，尽管通常说不正确"，但我怀疑这种情况很快就会改变-有关更多详细信息，请在shell/命令提示符下使用以下简单的单行代码:

In practice many functions of os.path are just string manipulation functions (which just happen to be especially handy for path manipulation) -- and since that's innocuous and occasionally handy, while formally speaking "incorrect", I doubt this will change anytime soon -- for more details, use the following simple one-liner at a shell/command prompt:

$ python -c"import sys; import StringIO; x = StringIO.StringIO(); sys.stdout = x; import this; sys.stdout = sys.__stdout__; print x.getvalue().splitlines()[10][9:]"

或者，对于Python 3:

Or, for Python 3:

$ python -c"import sys; import io; x = io.StringIO(); sys.stdout = x; import this; sys.stdout = sys.__stdout__; print(x.getvalue().splitlines()[10][9:])"
