python – How to convert list of tuples to multiple lists?

The built-in function zip() will almost do what you want:

>>> list(zip(*[(1, 2), (3, 4), (5, 6)]))
[(1, 3, 5), (2, 4, 6)]

The only difference is that you get tuples instead of lists. You can convert them to lists using

list(map(list, zip(*[(1, 2), (3, 4), (5, 6)])))

From the python docs:

zip() in conjunction with the * operator can be used to unzip a list:

Specific example:

>>> zip((1,3,5),(2,4,6))
[(1, 2), (3, 4), (5, 6)]
>>> zip(*[(1, 2), (3, 4), (5, 6)])
[(1, 3, 5), (2, 4, 6)]

Or, if you really want lists:

>>> map(list, zip(*[(1, 2), (3, 4), (5, 6)]))
[[1, 3, 5], [2, 4, 6]]

Use:

a = [(1,2),(3,4),(5,6),]    
b = zip(*a)
>>> [(1, 3, 5), (2, 4, 6)]
