I updated your code to current state of affairs (Python 3, current task formulation with variables n adn m, fixed minor errors):

N_guys = n
guys_lst = topic

pairs_max_top = [bin(int(guys_lst[i],2) | int(guys_lst[j],2)).count('1') for i in range(N_guys-1) for j in range(i+1,N_guys) ]
max_top=max(pairs_max_top) 
max_team_num=pairs_max_top.count(max_top)

return [max_top,max_team_num]
