Great coding challenge to learn object oriented programming.

Approved.

python new test framework is required. updated in this fork

Description says "Only positives integers will be used", yet 0 is generated sometimes.

I have learned few new things about python while solving. Good kata!

Im not at this top level stuff but how do you access the Foo() class within the test cases? If I try making my own it doesn't work as the test cases require the class object specifically initilized within the test cases its self.

the link in the description points to the docs for Python 2.7, which is quite ancient. it should be upgraded to more recent docs

Hello There, i am trying to do this kata but get stuck on when the with statement is executed

i am not able to get to the enter method, even if i do my custom contextmanager...

is there any tips you can provide ?

My solution works locally, but fails when submitted.

This was a great kata, overall.

But I would definitely write up some more tests that include other classes being inherited by base classes.

for example.

class Person(metaclass = Meta):
    def __init__(self, name):
        self.name = name

    def getName(self):
        return self.name

class Bob(Person):
    def __init__(self):
        self.n = 1
        super().__init__('Bob')

    def bob_get(self):
        return self.n


b = Bob() # should register two __init__ calls
b.a = 2 # set
b.a # get
b.bob_get() # get for 'n' along with get for method call and method call itself

There is a solution that passes your tests but doesn't pass this one so I had to improve the solution.

So to prevent the incomplete or incorrect code from passing and making this kata a bit more complete, I would add up those tests.

Regardless of that - Excellent stuff!

Really enjoyed this Kata! Metaclasses are so cool. Thanks!

This kata is amazing and I learned a lot about Metaclass. Thanks!

Ranks can't be changed.

Kata is nice, but compaired to other 4 kyu's I've tried it is too simple. Maybe move to 5 kyu?
