The function below takes one parameter: a list of integers (num_list). Complete the function to count how many of the numbers in the list are even. As discussed in lecture, this question uses the 'visit every element of a collection' pattern, the 'is a number even' pattern, and the 'count' pattern.

The function that takes one parameter and count the numbers that are even number is written as follows:

def count_even_number(num_list):

   count = 0

   for i in num_list:

       if i%2 == 0:

           count += 1

   return count

print(count_even_number([10, 33, 53, 45, 7, 6]))

A function named  count_even_number is declared and the parameter is num_list.

Then a variable named count is created and initialise with 0.

Then a for loop is used to loop through the num_list.

if the remainder of when the lopped value is divided by 2 is equals to zero the count variable increase.

Then the count is returned.

The print function is used to call the function with it parameter.

following are the method definition to this question:

def count_even_integers(num_list): #defining a method, that takes num_list as a parameter  

   even_count = 0 #defining variable and assign 0

   for x in num_list: #defining loop that check all numbers  

       if(x%2==0): #define condition to check even number

           even_count =even_count+ 1 # increment value by 1

   return even_count # return even_count value

num_list=[10, 20, 30, 40] #defining list of integer

x=count_even_integers(num_list) #calling the method store its return value

print (x) #print value

Output:

4

Explanation:

In the given python program, a method "count_even_integers" is defined, that passes the value, that is "num_list" in its, inside the method, a variable "even_count" is declared, that assigns the value that is 0.

Inside the method, a for loop is declared, that uses the conditional statement in which and if block is used, that checks even number condition. Inside the block, even_count value is increment by one and return its value, then we call the method, and store the value in variable x and print its value.
