Python Program to print unique values from a list

PythonServer Side ProgrammingProgramming

Given a list, our task is to print all the unique numbers.

Example

Input:A = [1, 2, 3, 4, 2, 1, 9]
Unique list is [1, 2, 3, 4, 9]

Algorithm

Step 1: Create user input list.
Step 2: Create an empty list.
Step 3: Traverse all elements in the list.
Step 4: Check the unique element is present or not.
Step 5: Append unique element one by one into that empty list.
Step 6: Display that list.

Example Code

# Python program to print unique values from a list

def unique(A):
   # intilize a null list
   uniquevalues = []

   # traversing the list
   for i in A:
   # check unique valueis present or not
   if i not in uniquevalues:
      uniquevalues.append(i)
      # print (A)
      for i in uniquevalues:
      print (i),

      # Driver code
      A=list()
      n=int(input("Enter the size of the List ::"))
      print("Enter the Element of List ::")
      for i in range(int(n)):
      k=int(input(""))
      A.append(k)

print("The unique values from the List is ::>")
unique(A)

Output

Enter the size of the List :: 6
Enter the Element of List ::
