s1 = [ 'A', 'B', 'C', 'D', 'E' ]
s2 = [ 'F', 'G', 'H', 'I', 'J' ]
s3 = []

for count in xrange( len(s1) + len(s2) - 1 ):
    try:
        operand = s2.pop()
    except IndexError:
        operand = None
    except:
        raise
    s3.insert(0,operand)
    print [ t for t in zip(s1, s3) if t[1] is not None ]
