Pause & Proceed - Python Programming Exercise

In this exercise, you will develop a Python program that writes the even numbers from 10 to 20, both inclusive, except 16. The program will implement three different methods to achieve this: Using a "while loop" and incrementing by 2 in each step, utilizing the "continue" statement to skip the number 16. Using a "while loop" and incrementing by 1 in each step, also employing "continue" to skip the number 16. Using an endless "while loop" with "break" and "continue" to stop the loop when the desired numbers are printed. This task will help you practice loops in Python, specifically how to control the flow of the loop using "continue" to skip iterations and "break" to exit the loop. You will also work with conditional statements to check for specific numbers like 16 and avoid printing them. By completing this exercise, you will improve your understanding of loop control and enhance your ability to handle edge cases in Python programming. These techniques are widely used in real-world applications to manage iterative processes efficiently.

Pause & Proceed

 Objective

Develop a Python program that writes the even numbers from 10 to 20, both inclusive, except 16, in 3 different ways:

Incrementing by 2 in each step (use "continue" to skip 16)
Incrementing by 1 in each step (use "continue" to skip 16)
Using an endless loop (with "break" and "continue")

 Example Python Exercise

 Copy Python Code 
#Incrementing by 2 in each step (use "continue" to skip 16)

# Initialize the counter variable
i = 10

# Use a while loop to display even numbers from 10 to 20, skipping 16
while i <= 20:
    if i == 16:
        i += 2
        continue
    print(i)
    i += 2

#Incrementing by 1 in each step (use "continue" to skip 16)

# Initialize the counter variable
i = 10

# Use a while loop to display even numbers from 10 to 20, skipping 16
while i <= 20:
    if i % 2 == 0:
        if i == 16:
            i += 1
            continue
        print(i)
    i += 1

#Using an endless loop (with "break" and "continue")

# Initialize the counter variable
i = 10

# Use an endless loop to display even numbers from 10 to 20, skipping 16
while True:
    if i > 20:
        break
    if i == 16:
        i += 2
        continue
    print(i)
    i += 2

 Output
