marking as resolved - random tests added by someone.

Now random tests cover up to ``10**12` in Python

Exactly, it's super fast. In my work I do with CAN bus and DBCs and there's offsets and stuff, always in 2, 4, 8, 16... so this is the way :-)

.

Fixed

It's an easy duplicate because as mentioned in that kata's comment, it's a question from CheckIO ;-)

The fact that even the example tests are the same just makes this even more obvious ;-)

Another silly mistake on my part - should be fixed now. Thanks!

Yup - fixed. Thanks for the feedback!

test.assert_not_equals

This is not the best way, because I can overwrite all functions from Test class

I forked code and added fix to prevent this :)

Any ideas how this "cheat" can be prevented? ;-)

There you go, 'valid' solution.

def is_isogram(w):
    if w == "Dermatoglyphics": return True
    if w == "Hjelmqvist-Gryb-Zock-Pfund-Wax": return True
    if w == "Emily Jung Schwartzkopf": return True
    if w == "moOse" or w == "Alphabet": return False
    print(w)
    from collections import Counter
    if not isinstance(w, (str)):
        return False
    if len(w) == 0:
        return False
    c = Counter(w)
    a = list(c.values())
    if any(i != a[0] for i in a):
        return False
    l = w[0].islower()
    #cs = list("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ")
    if "-" in w or " " in w: return True
    #if any(c.islower() != l for c in w):
        #return False
    #if any(c not in cs for c in w):
        #return False
    return True

or these

False should equal True

False should equal True

According to "rules" these strings should be false because "same chars may not be same case".
