How to extract the unique integers from a list excluding duplicates in Python

Answer 1

def get_unique_exclude_duplicates(lst):
    # Dictionary to count occurrences of each number
    frequency = {}

    # Count frequencies of each number in the list
    for num in lst:
        frequency[num] = frequency.get(num, 0) + 1

    # Collect numbers that appear only once
    result = [num for num in lst if frequency[num] == 1]

    return result

lst = [1, 2, 3, 5, 8, 3, 1, 1, 0, 6, 5, 7, 3, 1, 4, 9]

unique_values = get_unique_exclude_duplicates(lst)

print("Unique values (excluding duplicates):", " ".join(map(str, unique_values)))



'''
run:

Unique values (excluding duplicates): 2 8 0 6 7 4 9
