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.

I have passed 5 tests and 0 failed, but error occurred:
Traceback (most recent call last):
File "main.py", line 17, in
test.expect(abs(actual-val) < 1e-12, "Expected %s == %s, but got %s" % (key, val, actual))
TypeError: unsupported operand type(s) for -: 'str' and 'int'
Is the problem in tests?
