Loop does not work in python

[ibreeden]

Yes indeed. The function will always return "2". Look sharp at your code:

    even2="2"
    ...
    clusterAssigments=even2
    return clusterAssigments

You should write comment lines (starting with "#") in your code for explanation, because I cannot understand what you are trying to achieve. But I can see there are problems with the following part:

    while ref==even1:
        clusterAssigments=even2
        if ref==uneven1:
            clusterAssigments=uneven1
        else:ref==even1 and ref==uneven3

In the while you compare an integer (ref) with a bool (even1). I checked it by placing print statements before the while loop.

    print("ref=" + str(ref))
    print("even1=" + str(even1))

Output:
ref=10
even1=True

So I can tell you: the loop will not execute. And if it would execute, how would it end? The line else:ref==even1 and ref==uneven3 is of course also not correct. You execute a boolean expression and do not assign it to anything.
I hope this helps you.
