I can't use them in HackerRank - they are no longer part of the standard library as of 2.12, I believe.Akshat Mahajan– Akshat Mahajan2016-10-26 01:22:39 +00:00Commented Oct 26, 2016 at 1:22

Yes, they were removed since 2.11. Too bad, because they are made for exactly this kind of problemcorvus_192– corvus_1922016-10-26 07:54:26 +00:00Commented Oct 26, 2016 at 7:54

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. design-patterns), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
