Question

Say i have a dictionary within a dictionary like so:

Allusers={
User1: {'Film1': Vote1, 'Film2': Vote2}
User2: {'Film1': Vote1, 'Film2'; Vote2}
...

}

I would need the logic/algorithm/formula to compare every person to the other persons, just once.
How would I need to approach this ?
Thank you.

Answer 1

from itertools import combinations

Allusers={
    'User1': {'Film1': 'Vote1', 'Film2': 'Vote2'},
    'User2': {'Film1': 'Vote1', 'Film2': 'Vote2'}
}

for comb in combinations(Allusers, 2):
    if Allusers[comb[0]] == Allusers[comb[1]]:
        print '{0} is same with {1}'.format(comb[0], comb[1])
