List of numbers of intercetions : Hi I have 2 lists of list
c=[[1,2], [2,3]]
b=[[1,2], [2,0]]
I need for the first item in list c compare it with the first item in list b and
add to the new list number of intercetion - 2
Than do the same with second elements of two lists and so on.
As a result - list of numbers of intercetion [2, 1...]  

    def intercect (l1,l2,count):
    count=0
    for i in l1:
        if i in(l2): count=count+1.0
        return count
    c=[[1,2], [2,3]]
    b=[[1,2], [2,0]]
    count1=[]
    count=0
    for i in c:
    for j in b:
        count1.append(intercect(i,j,0))
