python new test framework is required. updated in this fork

interesting one

Geometric progression...Maths x-x

I think this is way too hard for kyu7... at least kyu6

Thanks for the help!! gmpy2 is also good!

Hi, just a hint... sympy is not installed but gmpy2 is ;).

https://gmpy2.readthedocs.io/en/latest/mpz.html

sympy is not a standard module, and it's not installed on Codewars.
List of installed modules can be found here: https://github.com/Codewars/codewars.com/wiki/Language-Python

Why codewars dosen't execute "sympy" module in python
it really helps this kata to solve

Ruby translation kumited :) please check and approve ~~

'-100000 <= lower < upper <= 100000
If lower is greater than upper, it should return 0
...
sum_primes(20, 4) = 0 # since lower is greater than upper'

Since given 'lower < upper' those example are wrong

Man, that is a lot but also thanks a lot.

• limit should be included. (considered it's done)
• add more edge cases. (considered it's done)
• snake_case usage. (done)
• specify the upper/lower limits. (What do you mean by this?)
• add more random test and more effective. (done)
• Improve the "complete solution". (Actually, because this is intended for beginners(7 or 8 kyu). I don't mind the limitation just up to 10**4. But still, I will change it later. It is good for future references.) (and do you mind if I use yours? because it is already in test cases ;-) )

Multiple suggestions:

• specify if the limits should be included, and then test it: e.g. (2, 7) --> [2, 3, 5, 7] or [3, 5] ?
• add some more edge cases, e.g. (5, 5)
• python function names are suggested to use snake_case, not camelCase (fixed)
• consider specifying the upper/lower limits of your tests
• add more random tests and make it more effective (done)
• impove your "complete solution" (becuase it's a bit slow ;-)
