python new test framework is required. updated in this fork

python: asertions must be wrapped with a test.it block, not a describe one (the prin can be replaced by a it block to resolved the issue below)

Tests should not produce (print) any output on the console.

You don't specify that the end date is inclusive. Usually and end date is exclusive.

There're already lots of katas asking the user to perform a trivial map/filter/reduce operation.
