#  To remove duplicate elements
defremoveduplicateele(A):
   newlist = []
   for n in A:
      if n not in newlist:
         newlist.append(n)
   returnnewlist
# Driver Code
A=list()
n=int(input("Enter the size of the List ::"))
print("Enter the number ::")
fori in range(int(n)):
   k=int(input(""))
   A.append(int(k))
print("THE NEW LIST IS ::>",removeduplicateele(A))

output

Enter the size of the List ::5
Enter the number ::
10
20
30
