How To Make A Program Run Continuously Python

In this tutorial, we will learn how to make a program run continuously in Python.

Making a program run continuously can be useful when you want to create a server, network applications, or simply monitor your applications for various events.

We will discuss techniques to achieve this and write a small continuous running Python program.

Step 1: Understanding the while loop

The most basic way to make a program run continuously is to use a **while loop**. In Python, a while loop runs a block of code until a specified condition is met. In the case of a continuously running program, we want the condition to be always true.

Here’s a simple example of a while loop in Python:

Step 2: Adding an exit condition

Now, let’s add an exit condition to our continuously running Python program. An exit condition is typically a user input or action that stops the program when met.

In our example, we will use the keyboard_interrupt exception, which occurs when the user presses Ctrl + C.

Here’s how you can add an exit condition using the keyboard_interrupt exception:

When the user presses **Ctrl + C**, the keyboard_interrupt exception is caught, and the program prints “Exiting…” before stopping.

Step 3: Adding functions and logic

Now we know how to create a simple continuous running program using the while loop and an exit condition. It’s time to add some logic and functionality to it.

For example, let’s create a program that continuously checks the current time every second and prints a message when it’s a specific time. We’ll use the datetime module and time.sleep() function from the time module:

This program will continuously check the current time every minute and prints a message when the time reaches 12:00 PM.


In this tutorial, we’ve learned how to make a program run continuously in Python using a while loop, an exit condition, and a simple time-checking function. This concept can be expanded and used in various applications such as servers, monitoring tools, and more. Be sure to experiment and adapt the logic to your specific needs.
