Question

Python is used here.

letters = ['p','q','r','s','p']
When i do below it shows none

print(letters.reverse())

Output: none

Can anyone check and help me on this

Answer 1

to explain Oscar Albornoz answer, reverse method changes the list and does not return a new list

you can do this however:
letters = ['p','q','r','s','x','y','z']
print(letters[::-1])

alternatively, you can use the reversed function:
print(list(reversed(letters)))

this will actually create a shallow copy of the list, and return it, keeping the original list unchanged

Answer 2

a = [1,2,3]
a.reverse()
print(a) #[3,2,1]

Answer 3

Here's the official blurb: https://docs.python.org/3/tutorial/datastructures.html

The same situation occurs with the list.sort(), list.remove() and list.insert() methods.
