In Python, while you are creating a program, you might have to end this program after you have met the conditions.
This article will act as a guide on the different ways that you can end a program in Python.
Why Will You Need To End A Program?
Programmers will need to end a program for many different reasons. The program will need to stop running at some point.
Most commonly, the program will need to be terminated if certain conditions have been either violated or met, and we don’t want to carry on with the rest of the program.
If a certain number of conditions have been met, then you may want to terminate the program. You may not want the program to continue.
Most programs do close down on their own when you reach the end of the program.
There are many different ways that you can close the program down on your own to stop the program from executing further.
So, let’s explore how we can end a program in Python.
End A Program Using The Quit() Function
The quit () function is a great way to end a program in python. It is an inbuilt function that is ready to use. It is really easy to use when you know how!
When you execute the quit() function, an exception is raised called the ‘SystemExit’. When this is triggered, the program will terminate.
You can only use this function under certain conditions and only if the module is installed.
For this reason, this is not the best way to end a program in Python.
As soon as this function is used, the execution of the program will end completely.
End A Program Using The Exit() Function
This function is very similar to the quit() function and works in a very similar way.
This also has to be installed in the site module so it is not advised that this is used when creating a program, just when you are using it.
End A Program Using The Sys.exit() Function
The sys.exit() function is already included when you download the original version of Python 3.
This is great because you don’t have to mess around with installing the module.
Instead, you can just use the sys.exit() function as soon as you open Python.
Using the sys.exit() module, this function will be used. When you execute it, it will take a string message as the optional input
Then the sys.exit() function will print the message displayed on the system before this is ended.
This function is a very useful thing to use as it can be used at any time without any concern about corruption.
End A Program Using The SystemExit Function
There is another way we can end the program in python if the sys.exit function do not work for us. The SystemExit function, in the simplest way listed, just terminates the program.
How Is Python Used?
Python is a programming language that can be used on any computer. It is often used to process data, images, numbers, and text. YouTube, NASA, and Google use Python every day.
People often think it is owned by Google, but this isn’t the case. They work hand in hand, but it is not owned by them.
Python plays a huge role in many different businesses, as well as the government.
Python is a language that is interpreted by a computer. This is different to some codes which convert information into a language that the computer can understand.
Instead, this language is used in the first place. This is known as scripting language.
Previously, it has been used for what is seen as trivial tasks, but Python is not similar to this.
Python has been used for many different things, all of which are very useful.
Frequently Asked Questions
Python is a programming language. It is very easily available, and it is easy to learn how to use. It is very simple to understand. The program was created in 1991 by Guido van Rossum.
He developed the software with the Python Software Foundation. The system was mainly developed for code readability and ease of understanding.
The syntax that was developed for it allows programmers to use less lines of code than other programmers.
Python is used in complicated and big programming projects across the world. The code is very simple and easy to understand to any programmer.
Perl is a lot harder to read, and the company struggles to make it so. Perl becomes confusing very quickly, whereas Python continues to be understandable and manageable no matter how far in you get.
Python has the readability and ease of use that companies like Perl do not have. Some people say that using Python over Perl is like having a product where the battery is included.
You simply have to turn it on and you will understand and benefit from it.
No, Python is not owned by Google. It is a project that was introduced by Guido van Rossum and owned by the Python Software Foundation.
Google uses the system where necessary, but Python is not owned by Google, but the rights to the software are licensed to the Python Software Foundation.

Final Thoughts
So, now we have explored all the different ways you can end a program in Python. The best way to terminate a program here is by using the sys.exit() function.
This is the best and easiest way to terminate a program. This is because both the quit() and exit() functions have to have the module imported separately.
They are not downloaded in the initial download of Python 3.
You should now have all the ideas on how to end a program in python.
