How to Exit an If Statement in Python [7 different ways]

In this Python tutorial, we will explore 7 different methods to exit an if statement in Python.

In Python programming, exiting from a condition is often necessary for various reasons, such as meeting specific conditions or handling errors effectively. Python provides several methods to exit from conditions gracefully.

These are 7 different methods to exit an if condition in Python :

  1. using exit()
  2. using return statement
  3. using break statement
  4. using try and except block
  5. using sys.exit()
  6. using quit()
  7. using os._exit()

Let’s see them all one by one using some illustrative examples:

How to exit an if statement in Python using the exit() method

The exit() method is a built-in method in Python that is used to terminate the program execution immediately. This helps us stop the program when a condition is met without further processing.

Here is how we can use the exit() method to exit an if statement in Python:

Code:

age = 10
if age > 5:
    print("Condition met. Exiting...")
    exit()
print("This won't be printed.")

In this example, if the age exceeds 5, it will immediately exit an if statement using the exit() method.

Output:

Condition met. Exiting...

How to break out of the if statement Python using the return statement

The return statement in Python exits the function immediately, transferring control back to the caller. In this context, it effectively breaks out of the if statement, preventing the execution of code should within the function.

Here is an example of exit an if statement in Python using return statement.

Code

def check_age(age):
    if age < 18:
        print("You are under 18.")
        return
        print("It should not print this statement")
    print("You are 18 or older.")

check_age(15)

In this example, if the age is under 18, the function prints a message and immediately returns, skipping any further code execution within the function like the statement “It should not print this statement” will not get printed.

Output:

You are under 18.

How to exit an if clause using a break statement

The break statement in Python is used to exit a loop prematurely. When encountered within an if clause, it immediately breaks out of the loop, regardless of any remaining iterations.

This is an efficient way to terminate the loop once a specific condition is met.

Code:

numbers = [1, 2, 3, 4, 5]
for num in numbers:
    if num == 3:
        print("Found 3. Exiting loop.")
        break
    print(num)

In this example, the loop iterates through the list of numbers in Python. When it encounters the value 3, the if clause triggers the break statement, causing an immediate exit from the Python loop.

Output

1
2
Found 3. Exiting loop.

Python exit if statement using try and except block

The try and except blocks are used for error handling in Python. Combined with an if statement, they can effectively exit the code block if an exception occurs.

In this context, if an error arises within the try block, the except block catches it and executes the specified actions, including exiting the Python program.

Code:

try:
    age = int(input("Enter a number: "))
    if age < 0:
        raise ValueError("Negative number entered.")
except ValueError as e:
    print("Error:", e)
    print("Exiting...")
    exit()
print("Number entered:",age)

In this example, the program attempts to convert user input into an integer within the try block in Python.

If the input is a negative number, a ValueError is raised, triggering the except block.

raise ValueError("Negative number entered.")

The program prints an error message inside the except block, exits gracefully, and terminates execution.

If no error occurs, the program continues executing beyond the try-except block.

Output:

Enter a number: -5
Error: Negative number entered.

Python breaking out of if statement inside using sys.exit() function

We use sys.exit() function to exit an if statement in Python. It can effectively break out of the block and terminate the program when called within an if statement.

This method ensures a clean and controlled exit from the program under specific conditions.

Code:

import sys

def validate_input(user_input):
    if not user_input:
        print("No input provided. Exiting...")
        sys.exit()

user_input = input("Enter something: ")
validate_input(user_input)
print("Input validated:", user_input)

The program validates user input within the validate_input() function in this example. If no input is provided, the function prints an error message and calls sys.exit() to terminate the program immediately.

Output

Enter something: 
No input provided. Exiting...

Python exit if statement

How to exit if condition in Python using quit() function

The quit() function is used to exit the Python interpreter. When called within an if statement, it effectively terminates the program execution, including any further code in the script.

This method provides a simple and direct way to exit the program when a specific condition is satisfied.

Code:

sales = 10000
if sales > 5000:
    print("Condition met. Exiting...")
    quit()
print("This won't be printed.")

In this example, if the sales exceed 5000, the program prints a message indicating that the condition is met and exits using the quit() function in Python.

Consequently, the statement “This won’t be printed.” is not executed, ensuring an immediate exit from the program when the condition is satisfied.

Output

Condition met. Exiting...

Python Breaking Out Of If Statement Inside

How to exit if condition code os._exit() function

The os._exit() function is used to exit the Python interpreter immediately. Unlike quit() or exit() functions, it performs no cleanup actions such as flushing buffers or executing cleanup handlers.

When called within an if statement in Python, it terminates the program without executing further code.

Code

import os

age = 10
if age > 5:
    print("Condition met. Exiting....")
    os._exit(0)
print("This won't be printed.")

In this example, if the age exceeds 5, the program prints a message indicating the condition is met and exits abruptly using os._exit(0) in Python.

As a result, the statement “This won’t be printed.” is not executed, ensuring an immediate exit from the program when the condition is satisfied, without any further processing or cleanup.

Output

Condition met. Exiting....

From the straightforward exit() method to the abrupt os._exit(), Python provides various tools to exit conditions gracefully or abruptly based on specific requirements.

Understanding these methods equips programmers with the flexibility to control program flow effectively and easily handle diverse scenarios.
