Compatibility based on 5 love language scores

love5.py

''' Compatibility computed from scores of 5 love languages ''' 

# the web quiz uses percentages
# https://www.5lovelanguages.com/quizzes/love-language

# scores for person 1
p1 = [ 10, 9, 6, 5, 0 ]

# scores for person 2 (must be in the same order)
p2 = [  3, 4, 9, 9, 5 ]

# by using the average as offset we can use raw scores from the old
# quiz, or percentages from the web quiz

avg = (sum(p1)+sum(p2))/10

# we subtract the median (6) from all vector components
p11 = sum([(x-avg)*(x-avg) for x in p1])
p22 = sum([(x-avg)*(x-avg) for x in p2])
p12 = sum([(p1[x]-avg)*(p2[x]-avg) for x in range(5)])
score = int(p12 / ((p11*p22)**0.5) * 100)

''' final score is the cosine of the angle between 2 vectors in R5
    probably want to avoid pairings that comes up negative as those
    are pointing more in opposite directions than the same. It is
    not clear what a good threshold is but I guess 30 to 50. '''
