Deepti, What you’re seeing happens because you are making changes (words.remove(z)) to the list while you are iterating over it (for z in words). If your goal is to print the original words, removed words and original words without removed words, you could do something like this using sets:
words = ['bbb', 'ccc', 'axx', 'xzz', 'xaa'] def front_x(words): # +++your code here+++ removed_words = [] for word in words: if word.startswith('x'): removed_words.append(word) print 'word is', word print 'original', sorted(words) print 'new', sorted(removed_words) print sorted(list(set(removed_words + words))) If you also wanted to get the original words after removing the removed_words, you could print them like this: print 'original - new', list(set(words) - set(removed_words)) Or you could even use list comprehension like this: print 'original - new', [word for word in words if word not in removed_words] -- Thanks, Nitin Madhok Clemson University CONFIDENTIALITY NOTICE This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain privileged and/or confidential information.
