Although this solution looks pretty short, using re is not a good idea in terms of resources. Re engine is very greedy for such a purpose, which is even reflected in the <a href="https://docs.python.org/3/howto/regex.html">python doc</a>: "Sometimes using the re module is a mistake. If you’re matching a fixed string, or a single character class, and you’re not using any re features such as the IGNORECASE flag, then the full power of regular expressions may not be required. Strings have several methods for performing operations with fixed strings and they’re usually much faster, because the implementation is a single small C loop that’s been optimized for the purpose, instead of the large, more generalized regular expression engine."
