How to split up a list of lists Python?

Question

I have a list of lists

myList = [[1,2,3],[4,5,6],[7,8,9,10]]

and I want to split it up into three separate list, each with their own name:

a = [1,2,3]
b = [4,5,6]
c = [7,8,9,10]

How do I do this?

Have you tried anything at all? – juanpa.arrivillaga Dec 01 '17 at 00:29 — juanpa.arrivillaga, Dec 01 '17 at 00:29

You could unpack it directly:

a, b, c = myList

To create new variables, you can use globals():

import string
myList = [[1,2,3],[4,5,6],[7,8,9,10]]
for i, value in enumerate(myList):
   globals()[string.ascii_lowercase[i]] = value

print(a, b, c)

Output:

([1, 2, 3], [4, 5, 6], [7, 8, 9, 10])

I was thinking we don't need a 3rd answer on this, but then I learned something! :) – Reblochon Masque Dec 01 '17 at 00:40
Not going to comment on the use of `globals()` :) Any reason not to just `for name, value in zip(string.ascii_lowercase, myList):`? – AChampion Dec 01 '17 at 05:59
