Suggestion: In the Python version, put a comment next to @countcalls telling users not to delete this line. If they do, they get a mysterious replicate.reset error, because of how the hidden tests have been implemented.

Approved

python new test framework is required. updated in this fork

Random tests have been added some time ago

"design a recursive function"

Can we add this example to the Kata description to make it clearer?

This kata is broken, none of the listed solutions work. replicate.reset() is the culprit.

My python code passes all 5 tests, but I'm getting Exit Code:1

Traceback (most recent call last):
File "main.py", line 15, in
replicate.reset()
AttributeError: 'function' object has no attribute 'reset'

Any ideas why? I'm not calling reset() anywhere in my code?

If you reset the trainer (which will erase your code), you'll see that there's a a decorator countcalls applied to the replicate function, and it's there for a reason.
