specifically thing.reverse()

Answer 2

This one only works with lists of unique elements:

L = [1,2,3,4,5]
M = [L[len(L)-L.index(i)-1] for i in L]

print(M)

Answer 3

L = [1,2,3,4,5]
M = [L[len(L)-1-i] for i in range(len(L))]

print(M)

>>>
[5, 4, 3, 2, 1]

Answer 4

L.reverse() and
L=L[::-1] are simple ways. Please tell me other ways for reverse it.

Answer 5
