Good day. Hope you are safe and wish the same with the present situation.
Need you help please in understanding the below function of Python. 
 
 
Steps - 
1. tried assigning the below values in the list and named it as a
2.if I print, it prints in the same sequence.
3.Tried assigning it to b by the command a.sort()
4.Tried printing b and it gave null.
5.But printed a now, and the values were sorted.
 
 
Please help me understand if we have any logic with in a list to sort the values after an iteration.
Please apologize if I had missed some basics and uncovered it. 
 
>>> a = [1,4,3,2,4,5,3,2]
>>> a
[1, 4, 3, 2, 4, 5, 3, 2]
>>> print (a)
[1, 4, 3, 2, 4, 5, 3, 2]
>>> b = a.sort()
>>> b
>>> print (a)
[1, 2, 2, 3, 3, 4, 4, 5]
>>>

I think it's an expected behavior.

`a.sort()` sorts the list itself in place, so it returns None.

If you want a sorted list returned, you need to use `sorted` function.
