Unpacking argument lists in Python
What I want to achieve is to transpose the list of list or tupple: original = [('First', 1, 3, 4), ('Second', 4, 5, 6)] to transposed = [('First', 'Second'), (1, 4), (3, 5), (4, 6)] With itertools.izip I can solve my problem: from itertools import izip transposed = izip(original[0], original[1]) But, what if my original list contains 1000 lists/tuples? Fortunately, in Python, you can unpack the list as arguments. So, what I need to do is just: transposed = izip(*original) Pretty amazing huh?
