Python break and continue

In this article, you will learn to use the break and continue statements to alter the flow of a loop.

What is the use of break and continue in Python?

In Python, break and continue statements can alter the flow of a normal loop.

Loops repeat over a square of code until the test articulation is bogus, however, in some cases we wish to end the present cycle or even the entire circle without checking test expression.

The break and continue statements are used in these cases.

Python break statement

The break statement terminates the loop containing it. Control of the program streams to the announcement following the body of the loop.

If the break articulation is inside a nested (loop inside another loop), the break statement will terminate the innermost loop.

The working of break statement in for loop and while loop is shown below.

Working on the break statement

Example: Python break

# Use of break statement inside the loop

for val in "string":
    if val == "i":
        break
    print(val)

print("The end")

Output

s
t
r
The end

In this program, we iterate through the “string” sequence. We check if the letter is I, upon which we break from the loop. Hence, we see in our output that all the letters up till I get printed. After that, the loop terminates

Python continue statement

The continue statement is used to skirt the remainder of the code inside a loop for the present iteration only. the loop doesn’t terminate however continues with the next iteration.

Syntax of Continue

How to continue statement works in python

Example: Python continue

# Program to show the use of continue statement inside loops

for val in "string":
    if val == "i":
        continue
    print(val)

print("The end")

Output

s
t
r
n
g
The end

This program is the same as the above example except the break statement has been replaced with continue.

We continue with the loop, if the string is i, not executing the rest of the block. Hence, we see in our output that all the letters except i get printed.
