What is a Python Function? 

In this tutorial, we discuss one of the most useful attributes of Python: the function. Python functions are considered “First Class” objects. A First Class object can be assigned to variables, stored in data structures, passed as arguments to other functions, or even return values from other functions. Other examples of First Class objects in Python are integers, strings, and dictionaries.

One of the most significant advantages of Python is how easy it is to reuse existing code. 

  • Need to talk to servers? Just import requests
  • Need to talk to a MySQL database? Import the mysql.connector software! 
  • Need to fly? Just import antigravity

Of course, these packages need to exist somewhere in your server, and installing them can be problematic without the right tools. Fortunately, that is a problem the Python developers have invested significant time investigating and correcting.

How to Install Python 2 & 3 on CentOS 8

Reading Time: 3 minutes

In this tutorial, we will consider how to enable both Python 2 and Python 3 for use on CentOS 8. In earlier distributions of CentOS, an unversioned Python command was available by default. 

When the CentOS installation was complete, it was possible to drop into a Python shell by simply running the “python” command in a terminal.

Paradoxically, CentOS 8 does not have an unversioned Python command by default.  This begs the question, why? RedHat states that this choice is by design “to avoid locking users into a specific version of Python.” Currently, RedHat 8 utilizes Python 3.6 implicitly by default, although Python 2.7 is additionally provided to maintain existing software.
