- Previous: Acknowledgments - Python for DevOps Acknowledgments
“DevOps, the combination of software development with information technology operations, has been a hot field during the last decade. Traditional boundaries among software development, deployment, maintenance, and quality assurance have been broken, enabling more integrated teams. Python has been a popular language both in traditional IT operations and in DevOps due to its combination of flexibility, power, and ease of use.”
“The Python programming language was publicly released in the early 1990s for use in system administration. It has been a great success in this area and has gained wide adoption. Python is a general-purpose programming language used in just about every domain. The visual effects and the motion picture industries embraced it. More recently, it has become the de facto language of data science and machine learning (ML). It has been used across industries from aviation to bioinformatics. Python has an extensive arsenal of tools to cover the wide-ranging needs of its users. Learning the whole Python Standard Library (the capabilities that come with any Python installation) would be a daunting task. Trying to learn all the third-party packages that enliven the Python ecosystem would be an immense undertaking. The good news is that you don’t need to do those things. You can become a powerful DevOps practitioner by learning only a small subset of Python.”
“In this chapter, we draw on our decades of Python DevOps experience to teach only the elements of the language that you need. These are the parts of Python DevOps that are used daily. They form the essential toolbox to get things done. Once you have these core concepts down, you can add more complicated tools, as you’ll see in later chapters.”
