// if you want to take single int input
a=int(input())
// if you want n elements of array a as input from console/user
a = list(map(int,input().strip().split()))
# u can also covert it to set,tuple etc
# ex. set(map(int, input().strip().split()))
NOTE: suppose if you want a list with duplicates removed
list(set(map(int, input().strip().split())))
also note map is a method and is not hashmap which is actually disct in python.
and ommitting .strip() in 2nd argument of map func might also work.
