I have four elements to compare with
A= [1,2,3,4]
B=[1,2]
C= [3,5,6]
D= [2, 4, 5, 6,7]
How do I compare which one has the greatest len?

You can use max with a key.
max(a,b,c,d,key=len)

I like this one line solution! neat! Well it is python after all

I always forget about the
key keywords. I really need to start making better use of this.You can use the len function, e.g.
len(A)
gives
4
So it would be something like:
len_a = len(A)
len_b = len(B)
len_c = len(C)
len_d = len(D)
max_length = max([len_a, len_b, len_c, len_d])
if len_a == max_length:
print 'A'
if len_b == max_length:
print 'B'
if len_c == max_length:
print 'C'
if len_c == max_length:
print 'D'

what if A and B have the same length?

@user2626540: edited ... now it gives multiple items if they have the same length.
