python - Comparing a list of lists with a list to find similar numbers -

here tried:

my_tickets = [ [ 7, 17, 37, 19, 23, 43],            [ 7, 2, 13, 41, 31, 43],            [ 2, 5, 7, 11, 13, 17],            [13, 17, 37, 19, 23, 43] ]  def lotto_matches(xs, my_tickets):    xi = 0 # used pick specific things lists    yi = 0 # used pick specific things lists    result = []    in my_tickets: # list of lists       x in xs: # picks          if my_tickets[i] == xs[x]: #not sure if statement suppose             result.append() # don't know goes in parenthesis     print (result)     return (result)  lotto_matches([42,4,7,11,1,13], my_tickets) 

i trying write function takes list of tickets , draw, , returns list telling how many picks correct on each ticket.

it supposed return [1,2,3,1] output wrong.

how can this?

you can use map , intersection this:

def lotto_matches(pick, my_tickets):     result = map(lambda x: len(set(x).intersection(pick)), my_tickets)     return result  print lotto_matches([42,4,7,11,1,13], my_tickets) 

where pick ticket match.

if using python 3, map returns iterator not want, you'll need

return list(result)
