nonPrime_lst(L) accepts a list L of integers ( >1 ) and returns a list that contains all the Nonprime numbers picked from L. For example, nonPrime_lst([2,4,5,7,10,11,12,15,19] should return [4,10,12,15]).

Answer #1

Solution:

def nonPrime_lst(L):
    nonprimes = []
    for i in L:
        n = i
        count = 0
        for j in range(1, n + 1):
            if n % j == 0:
                count = count + 1
        if count != 2:
            nonprimes.append(n)
    return nonprimes


print("List of non prime numbers is", nonPrime_lst([2, 4, 5, 7, 10, 11, 12, 15, 19]))

    1. Write a function called ordinal_sum that accepts a string argument and returns the sum of the ordinal values of each character in the string. The ordinal value of a character is its numeric Unicode code point in decimal. 2. Write code that creates a Python set containing each unique character in a string named my_string. For example, if the string is 'hello', the set would be {'h', 'e', 'l', 'o'} (in any order). Assign the set to a variable...

    Write function all_coprime_pairs( ) which takes as input a list, L, with positive unique integers (i.e. no duplicated integers), and should return: 1. List (of tuples) containing all pairs of numbers in L that are coprime. 2. Empty list, If no pair of numbers in L is coprime. Your solution must include a function call to the function coprime designed in the previous question. The order of the tuples or the order of the two numbers within the tuples is...
