Python - Unsupported type(s) : range and range

Question

I\'m getting this strange error trying to run a script, the code appears to be correct but it seems python (3) didn\'t liked this part:

        def function(         


        

Answer 1

As others have pointed out the problem is that in Python 3, range() returns an iterator not a list like it does in Python 2.

Here' one workaround: Add something like the following function:

def non_zero_range(lower, upper):
    ret = list(range(lower, upper))
    ret.remove(0)
    return ret

and then change the second Racional() call argument from:

coeff(choice(range(-30,0)+range(1,30)))

to simply:

coeff(choice(non_zero_range(-30,30)))

You will have something that would work in both Python 2 and 3.
