Question

a)     Write a program that reads a list of integers, and outputs all even integers in the list. For example, if the input list is [1, 2, 13, 14, 25], the output list should be [2, 14].

b)    Based on your code for part (a), write a program that reads a list of integers, and reports True if all numbers in the list are even, and False otherwise. Example: For input [1, 2, 13, 14, 25], the output should be False.

Your program must define and call the following two functions.

evens() returns all even integers in the list are even.

all_even() returns True if all integers in the list are even and false otherwise.

Your code could look like this

#Your name here

def evens(thelist):
#your code goes here



def all_even(thelist):
#your code goes here



evens([1, 2, 13, 14, 25]) #should return [2,14]
all_even([1, 2, 13, 14, 25]) #should return False

def evens(thelist):
    evens_l = []
    for num in thelist:
        if num % 2 == 0:
            evens_l.append(num)
    return evens_l


def all_even(thelist):
    return len(evens(thelist)) == len(thelist)


def main():
    thelist = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
    print('The List:', thelist)
    print('Evens in the list:', evens(thelist))
    print('Is all even?', all_even(thelist))
    print('Is all even?', all_even(evens(thelist))) # passing the even list to check if its all evens


main()
