The break and continue Statement

In Python, the break and continue statements are used to control the flow of a loop.

The break statement is used to exit a loop prematurely if a certain condition is met. When the break statement is encountered inside a loop, the loop is immediately terminated and the program execution resumes at the next statement after the loop. Here’s an example of how to use the break statement in a while loop:

x = 0
while x < 10:
    print(x)
    x += 1
    if x == 5:
        break

In this example, the while loop will iterate 10 times, but the break statement is used to terminate the loop prematurely when x equals 5. The output of this code will be:

0
1
2
3
4

The continue statement, on the other hand, is used to skip over the rest of the code in a loop for a particular iteration if a certain condition is met. When the continue statement is encountered inside a loop, the current iteration of the loop is terminated, and the program execution resumes with the next iteration of the loop. Here’s an example of how to use the continue statement in a for loop:

for i in range(10):
    if i % 2 == 0:
        continue
    print(i)

In this example, the for loop will iterate over the range of numbers from 0 to 9. When i is even (i.e., i modulus 2 equals 0), the if statement is true, and the continue statement is executed, causing the loop to skip over the print statement for that particular iteration. Therefore, the output of this code will be:

1
3
5
7
9

Both break and continue statements are useful tools for controlling the flow of loops in Python. However, it’s important to use them judiciously to avoid creating code that is difficult to understand or maintain.
