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.
There are already many arithmetic expression search katas. What makes this kata special from those ones?
Messages from tests are not really helpful:
ValueError: list.remove(x): x not in list
, orValueError: not enough values to unpack (expected 3, got 1)
, orTypeError: cannot unpack non-iterable int object
,It would help if tests did some preliminary checks and explained what is an actual problem rather than crashin.
