  glob python modules unix files

  • 11.7 glob --  Unix style pathname pattern expansion 

      

       

     The glob module finds all the pathnames matching a specified pattern according to the rules used by the Unix shell. No tilde expansion is done, but *, ?, and character ranges expressed with [] will be correctly matched. This is done by using the os.listdir() and fnmatch.fnmatch() functions in concert, and not by actually invoking a subshell. (For tilde and shell variable expansion, use os.path.expanduser() and os.path.expandvars().)   

     

       

    glob(

    pathname)

     

     Return a possibly-empty list of path names that match pathname, which must be a string containing a path specification. pathname can be either absolute (like /usr/src/Python-1.5/Makefile) or relative (like ../../Tools/*/*.gif), and can contain shell-style wildcards. Broken symlinks are included in the results (as in the shell). 

      

     

       

    iglob(

    pathname)

     

     Return an iterator which yields the same values as glob() without actually storing them all simultaneously.  New in version 2.5.  

      

     For example, consider a directory containing only the following files: 1.gif, 2.txt, and card.gif. glob() will produce the following results. Notice how any leading components of the path are preserved.  

     

    >>> import glob >>> glob.glob('./[0-9].*') ['./1.gif', './2.txt'] >>> glob.glob('*.gif') ['1.gif', 'card.gif'] >>> glob.glob('?.gif') ['1.gif']
