A lottery ticket contains five unique numbers. A set of unique numbers does not contain repeated elements. The winning combination of this lottery is chosen by picking five unique numbers. Define a function matches(ticket, winners) that takes two lists and returns an integer that says how many numbers the two lists have in common. In []: matches([11, 12, 13, 14, 15], [3, 8, 12, 13, 17]) Out[]: 2

Explanation:

You can use the SET INTERSECTION method.

Because intersection will give u the common elements.

And we can get their length by using len method.

Here is what the code would look like,

def matches(tickets, winner):

tickets = set(tickets)

winner = set(winner)

return len(tickets.intersection(winner))
