Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
"best practice" would be to use the result of count() instead of going through the whole string twice.
Less clear and also 3 times slower than your solution :P

encoding, strip "=="
decoding, add "=="
Letters for variable names + unclear description, GL !
Python please ...
