Python’s break statement breaks the loop in which the statement is inserted. A continue Python statement skips a single iteration in a loop. The break and continue statements can be used in a for or while loop.

You may want to skip a particular iteration of a loop or end a loop completely. This is where the break and continue statements come in. These statements allow you to control how a loop unfolds.

The break statement built into Python allows you to exit a loop when a condition is met. The continue statement allows you to skip part of a loop when a condition is met. In this guide, we’ll see how to use the break and continue Python statements.

Updating loops

Programmers use loops to automate and repeat similar tasks. One of the most commonly used loops is an for loop. An for loop repeats a block of code until a certain condition is met. Here is the syntax of a for loop in Python:

The following for loop will iterate through a list of numbers from 0 to 2 and print them:

Our code returns the following:

Our code example printed the value i three times. This is a basic example of a cycle. Shows how a programmer can use loops to perform repetitive tasks on a block of code.

Python Break statement

The Python break statement breaks the loop in which the statement entered. When a break statement is executed, the statements after the contents of the loop are executed.

A break statement can be placed inside a nested loop. If a break statement is displayed in a nested loop, only the inner loop will interrupt execution. The outer loop will continue to run until all iterations have occurred or until the outer loop is aborted with a break statement.

You can use break statements to break out of a loop when a specific condition is met. You declare an break statement in your loop, usually under an if statement.

Break Python Example

For example, you may have a list of student names to print. to stop after printing the middle name. This will allow you to verify that the program is working. Here is an example of a program that uses a break statement to do this:

First , we declared a Python list . This list contains the names of the students in the class. We then created a for loop. This loop displays the name of each student in the Python shell.

In our for loop, we’ve added a break statement. This instruction will be executed if a student has the value of index 2 in our list. When the break statement is executed, the loop breaks.

Our code returns the following:

Our program prints the names of the first two students (who have the index values ‚Äã‚Äã and 1 in our table) . When the program has reached the student with the index value 2, the cycle is terminated. The Python print at the end of our executed program.

We have used an else clause to tell our program what to do if our condition is not met. If our condition is not met, the name of the student we are iterating on is displayed on the Python console.

break statements cause a program to terminate a loop. The program continues to execute the following instructions in a main program after the loop has stopped.

Python continue statement

The continue statement indicates a loop to continue the next iteration. Any code following the continue statement is not executed. Unlike a break statement, a la L ’continue statement does not completely terminate a loop.

You can use a continue statement in Python to skip part of a loop when a condition is met. loop will continue to run. You use continue statements inside loops, usually after an if statement.

Continue Python example

Let & rsquo; s use an example to illustrate how the continue statement works in Python. In the example below, we use a continue statement to ignore the printing of the middle name in our table, then count nua the iteration:

Our code returns the following:

Our continue statement is executed when a condition external is triggered. In our program, this condition is "student == 2". When student equals 2 our program stops executing the loop iteration .

Our program continued to cycle through the items in the following list after continuing education was run. If we had used a break statement, our loop would have stopped completely.

The continue statement has several use cases. For example, let’s say you validate the data. You may want your loop to iterate over if a value is empty. This is because an empty value could interrupt the flow of validation code.

Conclusion

When working with loops in Python, you might want to skip an iteration or break your loop entirely. This is where the continue and break statements come in handy, respectively.
