Python Basics : Penetration testers and cybersecurity analysts often get into the situation of having to do repetitive work that takes away precious time from their active focus. Examples of such situations can be scanning targets, doing intensive enumeration, subdomain discovery, reconnaissance, and more.
This is where programming languages like Python become extremely useful. Mastering Python allows you to take your hands off these repetitive and mundane tasks, automate them through code (and make them faster) so that you can focus on the really mentally challenging aspects of your penetration testing and cybersecurity projects.
This course is the first in a two-course series that together will develop your Python skills and enable you to apply them in cybersecurity and penetration testing.
What is Python?
Python is a popular programming language. It was created by Guido van Rossum, and released in 1991.
It is used for:
- web development (server-side),
- software development,
- system scripting.
What can Python do?
- Python can be used on a server to create web applications.
- Python can be used alongside software to create workflows.
- Python can connect to database systems. It can also read and modify files.
- Python can be used to handle big data and perform complex mathematics.
- Python can be used for rapid prototyping, or for production-ready software development.
- Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc).
- Python has a simple syntax similar to the English language.
- Python has syntax that allows developers to write programs with fewer lines than some other programming languages.
- Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick.
- Python can be treated in a procedural way, an object-oriented way or a functional way.
Good to know
- The most recent major version of Python is Python 3, which we shall be using in this tutorial. However, Python 2, although not being updated with anything other than security updates, is still quite popular.
- In this tutorial Python will be written in a text editor. It is possible to write Python in an Integrated Development Environment, such as Thonny, Pycharm, Netbeans or Eclipse which are particularly useful when managing larger collections of Python files.
Python Syntax compared to other programming languages
- Python was designed for readability, and has some similarities to the English language with influence from mathematics.
- Python uses new lines to complete a command, as opposed to other programming languages which often use semicolons or parentheses.
- Python relies on indentation, using whitespace, to define scope; such as the scope of loops, functions and classes. Other programming languages often use curly-brackets for this purpose.
Who this course is for:
- You want to get into cybersecurity and need a skill (Python) to place ahead of your competition.
- You already work in cybersecurity and need Python skills to get your work done more efficiently.
- You are a business owner and want to learn one of the easiest programming languages out there.
- You are a developer who wants to get into cybersecurity and penetration testing.
- No prior requirements or prerequisites are needed.
