In my opinion, this kata does not test your algorithmic skills as your understanding of the binomial theorem. Sure, there are some tweaks to the problem, where I had to use some 'if's at the beginning but overall, nothing higher than 4 kyu. I was even considering on voting for 5 kyu. But then I thought about it for a while and decided that 4 kyu was pretty justified. Nice kata tho.
thanks for the kata ! but "given to you as a string in the form of "(ax + b)"" instruction is very misleading.
we are constructing all the code about "(ax + b)" form. but tests are asking us (5,3) this is very destructive,
atleast please add the test screen (5,3) and the developers understand what is asking ? for this way.
and also 4-5 point for this kata very unsatisfiying.
results are ok but there is a warning ! I dont know why ?
test.assert_equals(ex_binomial("5", 2).replace(" ", ""), "25") AttributeError: 'int' object has no attribute 'replace'
Because your code should return a string instead of an int?
thanks... u saved my life :)
Python 3 should be enabled.
Needs random tests.

I recycled my solution, adding only a tiny wrapper.
I actually liked this one more, than the other. It feels more concise and to-the-point. Also, the other one is severely overranked, IMHO.
