I wish to do what is described in this previous question but instead of lists
a,b,c I have
i number of lists (that is set based on user input):
How can I change the code from this question (shown below) to work with
i number of lists?
>>> a = [1, 2, 3, 4] >>> b = [2, 3, 4, 5, 6] >>> c = [3, 4, 5, 6, 10, 12] >>> elements_in_all = list(set.intersection(*map(set, [a, b, c]))) >>> elements_in_all [3, 4]
The issue I have is i don’t know how many lists I have in advance! needs to be iterable somehow
if you get input from the user, try to store it in the list of lists,like
lists = [[1,2,3], [1,2]]
then, use that variable instead of [a, b, c], map internally iterates all these lists and convert them to set.
li = [[1,2,3], [1,2]] print(list(set.intersection(*map(set, li))))
