I should really wait until I've had some coffee. Not continue, but break!


for i,line in enumerate(linelist):
   line = line.split()
   for k in line:
     if keyword.iskeyword(k):
       total += line.count(k)
       print "The word '%s' belongs in line num: %d" % (k, i+1)
       break

print "Total keyords are: %d" % total
