Write a Python Program to Print Even Numbers in a List using For Loop, While Loop, and Functions with a practical example. You can use the loop to iterate the list items and the If statement to check whether the list item is divisible by 2. If True, even number, so, print it.

Python Program to Print Even Numbers in a List using For Loop

In this Python program, we are using For Loop to iterate each element in this List. We are using the If statement inside the loop to check even numbers.

NumList = [] Number = int(input(“Please enter the Total Number of List Elements: “)) for i in range(1, Number + 1): value = int(input(“Please enter the Value of %d Element : ” %i)) NumList.append(value) print(“\nEven Numbers in this List are : “) for j in range(Number): if(NumList[j] % 2 == 0): print(NumList[j], end = ‘ ‘)

In this Python program, the user entered list elements = [22, 56, 7, 87]

For Loop – First Iteration: for 0 in range(0, 4)

The For Loop condition is True. So, Python enters into the If Statement.

if(NumList[0] % 2 == 0) => if(22 % 2 == 0) – Condition True

This Number will print.

Second Iteration: for 1 in range(0, 4) – Condition is True

if(NumList[1] % 2 == 0) => if(56 % 2 == 0) – Condition True

This Number will print.

Third Iteration: for 2 in range(0, 4) – Condition is True

if(NumList[2] % 2 == 0) => if(7 % 2 == 0) – Condition is False

This Number is skipped.

Fourth Iteration: for 3 in range(0, 4) – Condition is True

if(NumList[3] % 2 == 0) => if(87 % 2 == 0) – Condition is False

This Number will skip.

Fifth Iteration: for 4 in range(0, 4) – Condition is False

So, it exits from the For Loop

Python Program to Print Even Numbers in a List using While loop

This example to print even numbers in a list is the same as the above. We just replaced the For Loop with a While loop, please don’t forget to increment the j value (j = j + 1).

NumList = [] j = 0 Number = int(input(“Please enter the Total Number of List Elements: “)) for i in range(1, Number + 1): value = int(input(“Please enter the Value of %d Element : ” %i)) NumList.append(value) print(“\nEven Numbers in this List are : “) while(j < Number): if(NumList[j] % 2 == 0): print(NumList[j], end = ‘ ‘) j = j + 1

Python Program to Print Even Numbers in a List using Functions

This list of even numbers programs is the same as the first example. However, we separated the logic using the Functions.

def even_numbers(NumList): for j in range(Number): if(NumList[j] % 2 == 0): print(NumList[j], end = ‘ ‘) NumList = [] Number = int(input(“Please enter the Total Number of List Elements: “)) for i in range(1, Number + 1): value = int(input(“Please enter the Value of %d Element : ” %i)) NumList.append(value) print(“\nEven Numbers in this List are : “) even_numbers(NumList)
