or maybe even this:
Apologies for the self-reply, its late here !
(a couple of typos fixed too! )
def scrambleFile(fname,action=1):
try:
f = open(fname, "r")
fname = '.'.join(fname.split('.')[:2])
if action:
ff = open(fname + '.scrambled', "w")
ff.write('\r\n'.join([scrambleLine(l) for l in f ]))
else :
ff = open(fname + '.descrambled', "w")
ff.write('\r\n'.join([descrambleLine(l) for l in f ]))
f.close()
ff.close()
except Exception, details:
print 'ERROR :: (%s)' % details
