Here is one simple way (you definitely want to use zip() here):

array1 = 'A','B','C','D'
array2 = 'E','F','G','H'
array3 = 'I','J','K','L'

for triplet in zip(array1, array2, array3):
    print ''.join(triplet)

You can also do it with map in python2:

array1 = 'A','B','C','D'
array2 = 'E','F','G','H'
array3 = 'I','J','K','L'
print("\n".join(map("".join, map(None, array1, array2, array3))))

Try this:

array1 = 'A','B','C','D'
array2 = 'E','F','G','H'
array3 = 'I','J','K','L'
for elems in zip(array1, array2, array3):
    print ''.join(elems)

It prints

AEI
BFJ
CGK
DHL

Edit: you could also just zip the 3 strings together instead of creating tuples and get the same output:

for elems in zip("ABCD", "EFGH", "IJKL"):
    print(''.join(elems))
