NO. Sorry if this was not very clear.

In teh above example- len(l1) = 10
len(l2) = 3

So, the dict can not have more than 3 keys from l1 with same value from l2 except the last element from l1 .

So 
a,b,c will have one key- say aR
d,e,f - bR
g,h,i,j- cR- j has key cR because the number l1 is not completely divisible by l2 and leave a remainder.
