Instead of importing this module directly, import os and refer to this module as os.path. The "os.path" name is an alias for this module on Posix systems; on other systems (e.g. Mac, Windows), os.path provides the same operations in a manner specific to that platform, and is an alias to another module (e.g. macpath, ntpath). Some of this can actually be useful on non-Posix systems too, e.g. for manipulation of the pathname component of URLs. iÿÿÿÿNtnormcasetisabstjoint splitdrivetsplittsplitexttbasenametdirnamet commonprefixtgetsizetgetmtimetgetatimetgetctimetislinktexiststlexiststisdirtisfiletismounttwalkt expandusert expandvarstnormpathtabspathtsamefilet sameopenfiletsamestattcurdirtpardirtseptpathseptdefpathtaltseptextseptdevnulltrealpathtsupports_unicode_filenamest.s..t/t:s:/bin:/usr/bins /dev/nullcCs|S(s6Normalize case of pathname.

For each directory in the directory tree rooted at top (including top itself, but excluding '.' and '..'), call func(arg, dirname, fnames). dirname is the name of the directory, and fnames a list of the names of the files and subdirectories in dirname (excluding '.' and '..'). func may modify the fnames list in-place (e.g. via del or slice assignment), and walk will only recurse into the subdirectories whose names remain in fnames; this can be used to implement a filter, or to impose a specific order of visiting. No semantics are defined for, or required of, arg, beyond that arg is always passed to func. It can be used, e.g., to pass a filename pattern, or a mutable object designed to accumulate statistics.
