Python: Combining a list of lists [duplicate]

Question

Possible Duplicate:
Flattening a shallow list in Python

Let's assume I have a list of lists.

mylistOfLists = [[1, 2], [3, 4], [5, 6], [7, 8]]

What is the most elegant way in python to get this result?

myCombinedList = [1, 2, 3, 4, 5, 6]

Thank you for any suggestions!

Answer 1

myCombinedList = []
[myCombinedList.extend(inner) for inner in mylistOfLists]

Or:

import itertools
myCombinedIterable = itertools.chain.from_iterable(mylistOfLists)
myCombinedList = list(myCombinedIterable)

Answer 2

res=[]    
for item in mylistOfList:
        res+=item
