Rounding in this context mean both UP and DOWN.

8 minutes = 15 minutes
7 minutes = 0 minutes

This is contrast to real life shift where it's always round up to avoid lawsuit. No woonder I kept failing the test.

Thanks for the kata.

Fixed in latest fork above

Approved!

Python test should use decorator syntax, fixed in this fork

Also implemented this suggestion, changing the input to list of 2-ples

Seems fixed

(Python) shifts should be a list of tuples.

Flow like a butterfly, sting like a bee

The quote is Float like a butterfly, sting like a bee ;)

One-liners are much less readable when they are this long. Just write the same code in 2 or 3 lines and one can actually read it quickly and easily.

If you choose to unlock the solution, you won't be able to gain any honor for solving it. It's best to use that as a last resort. At the very least, Google is helpful!

The variable has been renamed to shifts

The kata has been updated and now tests for this. Thank you for your input!

Damn. You're right. Good catch

the argument in the solution setup could/should be named clocks or maybe better shifts (but plural in any case)

Needs edge case test.assert_equals(get_hours([["12:01am", "3:00am"], ["3:00pm", "12:00pm"]]), [3.0, 21.0]). At least 3 existing solutions fail at this test.
