The scope of the system administrator role has changed dramatically over the years. The number of systems supported by a single engineer has also increased. As such, it is impractical to handcraft each installation, and there is a need to automate as many tasks as possible. The structure of systems varies from organization to organization, therefore system administrators must be able to create their own management tools. Historically, the most popular programming languages for these tasks were UNIX shell and Perl. They served their purpose well, and I doubt they will ever cease to exist. However, the complexity of current systems requires new tools, and the Python programming language is one of them.
Python is an object oriented programming language suitable for developing large-scale applications. Its syntax and structure make is very easy to read, so much so that the language is sometimes referred to as “executable pseudocode.” The Python interpreter allows for interactive execution, so in some situations, you can use it instead of a standard UNIX shell. Although Python is primarily an object-oriented language, you can easily adopt it for procedural and functional styles of programming. Given all that, Python makes a perfect fit as a new language for implementing system administration applications. There are a large number of Linux system utilities already written in Python, such as the Yum package manager and Anaconda, the Linux installation program.
