What is a Python script?

Let's start with the very basics of writing and executing a Python script. What is a Python script? It is a simple text file that contains a series of organized commands written in a formalized language. The text file has the extension .py, but other than that, there is nothing to distinguish it from any other text file. It can be opened using a text editor such as Notepad or Wordpad, but the magic that is Python does not reside in a Python script. Without the Python interpreter, a Python script cannot be run and the commands it contains cannot be executed.
