Why the code in description giving "None" as a output ?

Question

a = [2,3,8,1,4]
print(a.sort())

Answer 1

because a.sort() sorts the elements in place and doesn't returns a new list or anything so printing it out returns None as nothing returned by calling that sort method

Answer 2

It is because the sort() modifies the list in place and doesn't return anything.
You could say-

a.sort()
print(a)
OR
print(sorted(a))

Answer 3

It's analogous to a.reverse() and reversed(a)

Answer 4

Avinesh what is function of sorted() ?
