One of the common questions aspiring [DevOps](https://scriptcrunch.com/tag/devops/) engineers ask is, do we need [**Python**](https://scriptcrunch.com/tag/python/) **for DevOps?** In this blog, we will explain to you why Python is essential in the DevOps world.

Information Technology is not like it used to be before. Most sysadmin tasks are **automated** using tools and scripting languages, including configuration management tools like **Chef, Puppet,** [**Ansible**](https://scriptcrunch.com/tag/ansible/), etc., and scripting languages like shell scripting, python, Ruby, etc.

Also, how people and teams work has changed drastically in recent years with philosophies such as [DevOps](https://devopscube.com/what-is-devops-what-does-it-really-mean/?ref=scriptcrunch.com) and methodologies like Agile.

Unlike before, different teams have started working together, and there is more and more automation from application [development](https://scriptcrunch.com/tag/development/) to deployment. Tools like [**Vagrant**](https://scriptcrunch.com/tag/vagrant/)**,** [**Docker**](https://scriptcrunch.com/tag/docker/)**, and** [**Kubernetes**](https://scriptcrunch.com/tag/kubernetes/) made developers' lives easy by reducing the time to set up and test development environments.

Cloud computing has drastically changed the way servers are provisioned. You don't need to wait days to get a server provisioned for your application deployment. With a few clicks, you will have your server ready for deployment.

The process gets easier by writing automation scripts for server provisioning and configuration. One such example is the [AWS python boto library](https://aws.amazon.com/sdk-for-python/?ref=scriptcrunch.com). Using Boto SDK, you can automate [AWS](https://scriptcrunch.com/tag/aws/) server provisioning.

## What does Python have to do with DevOps?

Gone are the days when DevOps engineers had to work with only [CI/CD](https://scriptcrunch.com/tag/ci-cd/) tools. Nowadays, companies want customized tooling and utilities to fit their CI/CD requirements. A simple example is a Python script to parse JSON to test a functionality in the CI/CD process.

It has led to a shift where people are involved in infrastructure operations, and CI/CD is asked to write custom utilities and modules to improve automation, release, and monitoring.

No company wants to babysit releases and pipelines. However, to develop custom utilities, you should know some level of programming, and the common language preferred in DevOps for such use cases is Python. Arguably [go](https://scriptcrunch.com/tag/%3Ca%20href=)/">Golang is also getting there because most of the modern DevOps tooling is built in Golang.

Also, with more and more MLOPS projects, DevOps engineers have to work with ML engineers, data engineers, and data scientists. Python is a common language among all these teams. As a DevOps engineer, you will be responsible for writing small utility and ML pipeline scripts.

So programming has become necessary for DevOps engineers, and Python is a great language. Also, the need for programming is well explained in this [comprehensive DevOps engineers guide](https://devopscube.com/become-devops-engineer/?ref=scriptcrunch.com).

According to the latest [StackOverflow Developer Survey](https://survey.stackoverflow.co/2023/?ref=scriptcrunch.com), 49.28% of developers prefer Python for scripting.

## Why Python For DevOps is Important?

Following are some of the main reasons why Python of DevOps is important

1. Python is one of the **best scripting languages**. The vast availability of Python libraries allows you to write scripts that can communicate with system internals, manipulate files and strings, manage networks, and so on.
2. Once you learn Python, you can write automation scripts in a well-structured way. Moreover, every [Linux](https://scriptcrunch.com/tag/linux/) system today comes bundled with Python.
3. Many DevOps teams use Python for building custom utilities, web apps for custom data visualization, and more. The main reason is that it's easy to learn, and you can develop utilities in days rather than months.
4. Besides, tools like **Ansible are purely written in Python**. You can develop custom Ansible modules for your automation tasks. Also, it is not limited to just Ansible; many tools written in Python let you create custom scripts to work with them better.
5. Most importantly, **during DevOps interviews**, you would be asked to solve programming or scripting challenges as part of the first round. Python is the best choice to clear those interview rounds.

So, there are enough reasons why you should learn Python to automate manual tasks.

## Learn Python By Building Web Apps

The best way for **DevOps engineers to learn Python** is by building applications.

So how to get started?

You can start with a simple **Python micro-framework like Flask** to understand how web applications work.

While building an application, you will learn about the front end ( UI ), backend ( middleware/ database connectivity, etc.), and some aspects of development that are helpful for devops engineers in their journey towards becoming one!

It might seem overwhelming initially, but once you finish the [tutorial](https://scriptcrunch.com/tag/tutorials/), you will gain some confidence in developing apps.

Following are some of the resources to get started.

1. [Python Flask tutorial: Build your first Flask application](https://scriptcrunch.com/recommends/python-flask-blog/).
2. [Flask: Develop Web Applications in Python](https://scriptcrunch.com/recommends/flask-development/)
3. [Learn the Flask Python Web Development Framework by Building an Ecommerce Platform](https://www.freecodecamp.org/news/learn-the-flask-python-web-framework-by-building-a-market-platform/?ref=scriptcrunch.com)

## Python Alternative for DevOps

One of the best alternatives for Python in DevOps is [Golang](https://go.dev/?ref=scriptcrunch.com). Most of the DevOps tools today are built using Golang. For example, Kubernetes, Terraform, and Docker are built using Golang.

Companies that build internal developer portals choose Golang for most of the tooling. Because the existing DevOps tools written in Golang can be easily extended for customization.

## Conclusion

This [guide](https://scriptcrunch.com/tag/guides/) covered why using Python for DevOps is essential for a DevOps engineer. The best way to start your DevOps journey is by learning to develop applications. If you know Python basics, you can start with a framework like a Python flask to understand the application workflow.
