How to unzip a list of tuples into individual lists?

Question

I have a list of tuples, where I want to unzip this list into two independent lists. I'm looking for some standardized operation in Python.

>>> l = [(1,2), (3,4), (8,9)] 

>>> f_xxx (l) 

[ [1, 3, 8], [2, 4, 9] ]

I'm looking for a succinct and pythonic way to achieve this.

Basically, I'm hunting for the inverse operation of zip() function.

Answer 1

You can use zip(*list):

>>> l = [(1,2), (3,4), (8,9)] 

>>> list(zip(*l)) 

[(1, 3, 8), (2, 4, 9)]
