I've made a python module file and uploaded in the SVN Repo (say string_utl.py which does string related operation). Is the anyway that I can access the the file Direclty for the SVN. Though I checkout the file Locally from the SVN to my computer and access it from there. But that not the point. I'm thinking of a local repository where all of my coworkers can access and modify the code. 
I though add the Lsvn location in the sys.path list but it didn't worked. 
I did it like this
sys.path.append ("http://lsvn/svn/lsvn/QRM_Helper/Helpful_Script/");
But didn't worked.
I tried it another way  like this
 urllib.urlopen(some_url) 
as I'm using Python 3 it  said to use urllib2.urlopen() but in my case it didn't worked either. It gave the following error that the module doesn't exist.
I just got the answer.  I'll use the Pysvn to checkout the repo to a local folder. And I'll add the folder to sys.path list. Using this I can access the folders module.
Thank everyone for helping me out
But I've a slight problem... I didn't had the admin right in my office computer(I'm using windows) so I installed the pysvn in my laptop and copied the lib files from my laptop to my office computer..
Though I can pysvn in my computer (Office comp).but the Python crashes for no certain reason when I access Pysvn.. Is the copy paste could be the reason for that.
Is there anyway I can access File from Online SVN in python?
