Those are tuples, not lists. Are you trying to create a list of tuples
from a, b, and c? If so, then zip does what you want:
>>> d = list(zip(a, b, c))
[(1, 'Red', 'a'), (2, 'Green', 'b'), (3, 'Blue', 'c')]
Or do you want all those elements merged into a single list?
>>> d = list(sum(zip(a, b, c), ()))
[1, 'Red', 'a', 2, 'Green', 'b', 3, 'Blue', 'c']
