python - Assign multiple values of a list

I am curious to know if there is a "pythonic" way to assign the values in a list to elements? To be clearer, I am asking for something like this:

myList = [3, 5, 7, 2]

a, b, c, d = something(myList)

So that:

a = 3
b = 5
c = 7
d = 2

I am looking for any other, better option than doing this manually:

a = myList[0]
b = myList[1]
c = myList[2]
d = myList[3]

Simply type it out:

>>> a,b,c,d = [1,2,3,4]
>>> a
1
>>> b
2
>>> c
3
>>> d
4

Python employs assignment unpacking when you have an iterable being assigned to multiple variables like above.

In Python3.x this has been extended, as you can also unpack to a number of variables that is less than the length of the iterable using the star operator:

>>> a,b,*c = [1,2,3,4]
>>> a
1
>>> b
2
>>> c
[3, 4]
