cleanup SVN-files

I copied folder from SVN. And it include svn-files. I deleted it with follow script:

import os

from subprocess import call

d = os.walk('my directory with SVN-tails')

for i in d:

print i # about folder

if i[0][-4:] == '.svn':

print i[0]

# delete SVN-files

call(['rm', '-R', i[0]])
