Testing needs to allow for fuzzy equality checking due to floating point errors.
Python:
General:
Please use new python test framework.
Done.
I have several suggestions to improve this Kata.
I suggest that the title be changes to 'Variance in the length of words in an array'. This is a little clearer.
The section describing the requirement to limit the result to four decimal places was not clear to me. I suggest that in addition to updating the description that you also add a test case illustrating this requirement.
I am unfamiliar with the term 'aleatory variable' and prefer the term 'random variable'.
Thanks for your contribution.
