Standard Module posixpath

posixpath This module implements some useful functions on POSIX pathnames.

$\begin{funcdesc}{basename}{p} Return the base name of pathname \var{p}. This is ... ...ond half of the pair returned by \code{posixpath.split(\var{p})}. \end{funcdesc}$

$\begin{funcdesc}{commonprefix}{list} Return the longest string that is a prefix ... ...st}. If \var{list} is empty, return the empty string (\code{''}). \end{funcdesc}$

$\begin{funcdesc}{exists}{p} Return true if \var{p} refers to an existing path. \end{funcdesc}$

$\begin{funcdesc}{expanduser}{p} Return the argument with an initial component of... ...path does not begin with a tilde, the path is returned unchanged. \end{funcdesc}$

$\begin{funcdesc}{expandvars}{p} Return the argument with environment variables e... ...ames and references to non-existing variables are left unchanged. \end{funcdesc}$

$\begin{funcdesc}{isabs}{p} Return true if \var{p} is an absolute pathname (begins with a slash). \end{funcdesc}$

$\begin{funcdesc}{isfile}{p} Return true if \var{p} is an existing regular file. ... ...nks, so both islink() and isfile() can be true for the same path. \end{funcdesc}$

$\begin{funcdesc}{isdir}{p} Return true if \var{p} is an existing directory. This... ...inks, so both islink() and isdir() can be true for the same path. \end{funcdesc}$

$\begin{funcdesc}{islink}{p} Return true if \var{p} refers to a directory entry t... ... symbolic link. Always false if symbolic links are not supported. \end{funcdesc}$

$\begin{funcdesc}{ismount}{p} Return true if \var{p} is a mount point. (This curr... ...ice --- is this test correct for all \UNIX{} and POSIX variants?) \end{funcdesc}$

$\begin{funcdesc}{join}{p\, q} Join the paths \var{p} and \var{q} intelligently: ... ...(\code{'/'}) inserted unless \var{p} is empty or ends in a slash. \end{funcdesc}$

$\begin{funcdesc}{normcase}{p} Normalize the case of a pathname. This returns the... ...lar function in \code{macpath} converts upper case to lower case. \end{funcdesc}$

$\begin{funcdesc}{samefile}{p\, q} Return true if both pathname arguments refer t... ...ber). Raise an exception if a stat call on either pathname fails. \end{funcdesc}$

$\begin{funcdesc}{split}{p} Split the pathname \var{p} in a pair \code{(\var{head... ...ains no slash, \var{head} is empty and \var{tail} equals \var{p}. \end{funcdesc}$

$\begin{funcdesc}{splitext}{p} Split the pathname \var{p} in a pair \code{(\var{r... ...tains no periods, and \var{ext} is empty or begins with a period. \end{funcdesc}$

$\begin{funcdesc}{walk}{p\, visit\, arg} Calls the function \var{visit} with argu... ...must be modified in place, using \code{del} or slice assignment.) \end{funcdesc}$
