How to compare each array in a set of binary arrays to an array that is outside the set

Question

I have a set of arrays. I also have a separate array (T) to compare each array in the set to. I've tried to use SequenceMatcher to do this but can't figure out how to loop it so that each array from the set gets compared to T.

This is for a fitness function for a genetic algorithm. I'm new to python and have tried several things. The code below may be laughable!

import difflib

parents = set()
while len(parents) < 5:
    a = tuple(np.random.choice([0, 1], size=(10)))
    if a not in parents: parents.add(a) # To make them different
parents = np.array([list(x) for x in parents])

print(pop_sp())

T = tuple(np.random.choice([0, 1], size=(20)))

for i in parents:
    fitness=difflib.SequenceMatcher(None,i,T)
    print(fitness.ratio)

I expect the output to be

[[0 0 1 0 0 0 0 1 1 0]  
 [0 0 0 1 1 0 1 0 0 0]  
 [1 0 1 1 1 1 0 0 1 1]  
 [0 0 1 0 0 1 1 0 0 0]  
 [1 1 0 1 1 0 0 1 0 0]] 

and the percent of similarity of each array to T.
but I am getting the following:

[[0 0 1 0 0 0 0 1 1 0]  
 [0 0 0 1 1 0 1 0 0 0]  
 [1 0 1 1 1 1 0 0 1 1]  
 [0 0 1 0 0 1 1 0 0 0]  
 [1 1 0 1 1 0 0 1 0 0]]

Answer 1

You have to call the fitness function

for i in parents:
    fitness=difflib.SequenceMatcher(None,i,T)
    ratios = fitness.ratio()
    print(ratios)
