Python Program To Get Unique Values From A List

Chapter: Python Last Updated: 27-09-2023 16:36:08 UTC

Program:

            /* ............... START ............... */
                
# Method 1: Using a Set

# Input list
my_list = [1, 2, 2, 3, 4, 4, 5]

# Convert the list to a set to remove duplicates
unique_values = set(my_list)

# Convert the set back to a list if needed
unique_list = list(unique_values)

print(unique_list)


# Method 2: Using a List Comprehension

# Input list
my_list = [1, 2, 2, 3, 4, 4, 5]

# Create a list with unique values using a list comprehension
unique_list = [x for x in my_list if my_list.count(x) == 1]

print(unique_list)


# Method 3: Using a Loop

# Input list
my_list = [1, 2, 2, 3, 4, 4, 5]

# Initialize an empty list to store unique values
unique_list = []

# Iterate through the original list
for x in my_list:
    # If the value is not already in the unique_list, add it
    if x not in unique_list:
        unique_list.append(x)

print(unique_list)


# Method 4: Using the collections.Counter class

from collections import Counter

# Input list
my_list = [1, 2, 2, 3, 4, 4, 5]

# Create a Counter object to count occurrences
counter = Counter(my_list)

# Extract unique values from the Counter object
unique_list = [item for item, count in counter.items() if count == 1]

print(unique_list)




                /* ............... END ............... */
        

Notes:

  • All of these methods will give you a list containing only the unique values from the input list. You can choose the method that best suits your needs and coding style.
