Question

PYTHON 3 HELP

Write a function find_common_elements(list_p,list_q) that accepts two lists, list_p and list_q, as parameters and returns a new list that contains only the elements that are common between two lists (without duplicates). Make sure your program works on two lists of different sizes. Demonstrate your function works by calling it with 2 different pairs of lists.

Pseudocode for find_common_elements(list_p,list_q):

INITIALIZE empty common_list
FOR EACH element e in list_p:
    IF e is in list_q:
        ADD e to common_list
RETURN common_list

Answer 1

def find_common_elements(list_p, list_q):
    common_list = []
    for num in list_p:
        if num in list_q and num not in common_list:
            common_list.append(num)
    return common_list


print(find_common_elements([1, 2, 3], [2, 3, 4, 5]))
print(find_common_elements([2, 3], [1, 5, 7]))
