Controlling Logic Flow Inside Loops

In loops, break and continue are keywords used to control the execution flow of the loop.

break immediately terminates the loop, while continue skips the current iteration and proceeds to the next one.


What is the break Keyword?​

The break keyword is used to immediately exit a loop when a certain condition is met.

For example, the while loop below has a condition count < 10, but the loop exits when count is 5.

Example of break Keyword
count = 0

while count < 10:
    print(count)
    # Increment count by 1
    count += 1

    # When count equals 5
    if count == 5:
        # Exit the loop
        break

Running this code will stop the loop when count reaches 5, resulting in the following output:

Output
0
1
2
3
4

What is the continue Keyword?​

The continue keyword immediately ends the current iteration and proceeds to the next iteration of the loop.

Example of continue Keyword
count = 0

while count < 5:
    # Increment count by 1
    count += 1
    # When count equals 3
    if count == 3:
        # Skip to the next iteration
        continue
    print(count)

When this code is executed, the iteration where count equals 3 is skipped due to the continue keyword, producing the following output:

Output
1
2
4
5

As shown above, utilizing the break and continue keywords allows you to control the logic flow within loops based on the specific conditions.
