I'm all for eliminating extra '.'s, but shouldn't extra '/'s be an error?
The ``parent()`` method returns an ancestor of the path::
>>> p.parent() PureNTPath('c:\\python33\\bin') >>> p.parent(2) PureNTPath('c:\\python33') >>> p.parent(3) PureNTPath('c:\\')
The ``parents()`` method automates repeated invocations of ``parent()``, until the anchor is reached::
>>> p = PureNTPath('c:/python33/bin/python.exe') >>> for parent in p.parents(): parent ... PureNTPath('c:\\python33\\bin') PureNTPath('c:\\python33') PureNTPath('c:\\')
What's the use-case for iterating through all the parent directories? Say I have a .dbf table as PureNTPath('c:\orders\12345\abc67890.dbf'), and I export it to .csv in the same folder; how would I transform the above PureNTPath's ext from 'dbf' to 'csv'? ~Ethan~
