```assume:
you have two list with the same size
L1 = [1,2,3]
L2 = [11,22,33]
you can zip the L1 and L2 into L
L = zip(L1,L2) # L = [(1,11),(2,22),(3,33)]
then you can process:
for x in L:
dosomething(x[0])...
dosomething(x[1])...
If you want to do something parallel processing then you should go to
Cheers,
