"glob" module in python

[Humble]

glob module in python is very useful when traversing through a directory structure and when searching for a pattern.. We have “os” module which got methods to achieve the same functionality, how-ever its not straight when glob do..

>>> import glob

>>> glob.__doc__
'Filename globbing utility.'
>>> 


glob module itself uses os, re, sys as shown below:

>>> dir(glob)
['__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '_unicode', 'fnmatch', 'glob', 'glob0', 'glob1', 'has_magic', 'iglob', 'magic_check', 'os', 're', 'sys']




glob's standard syntax is glob(pattern) .
glob(pattern) returns a list of all files matching a given pattern.

>>> glob.glob("/home/hchiramm/*.c")
['/home/hchiramm/checl.c', '/home/hchiramm/d.c', '/home/hchiramm/ch.c', '/home/hchiramm/h.c']



As you can see above, glob returns a list which contains the result. how-ever its possible to get a "generator" object from glob by calling its "iglob" method as shown below.

>>> glob.iglob("/home/hchiramm/*.c")
<generator object iglob at 0x7f6839012910>
>>>
