Python for Red-Blue Teams from Scratch 2022

Explore Python as an offensive programming language for red teams and a defensive programming language for blue teams, mastering core and advanced concepts across four sections.

Explain why Python is an easy programming language for learning, open source, and platform independent, with Python 2 and 3, and demonstrate interactive and scripting modes, including print and variables.

Explore variables in Python, learn how memory stores values, and identify primitive data types—integers, strings, floats, and booleans—along with type checks and user input.

Explore Python string handling for red-blue teams, from concatenation and f-strings to common methods like lower, upper, strip, find, and split, plus escape and raw strings.

Master Python lists as mutable data structures, covering creation, indexing, and appending elements. Learn unpacking, iteration with for loops, and key list methods like insert, remove, sort, and enumerate.

Explore tuples in Python: understand immutability, speed over lists, create them with or without parentheses, and use commas to define a tuple, with unpacking, indexing, and converting lists.

Master the Python range function for loops, using start, stop, and step to generate number sequences. Learn to iterate, reverse, and use positive or negative steps.

Explore Python dictionaries as key-value stores mapping keys of various types to values, created by literals or dict(), accessed with get and in, and viewed via keys, values, and items.

Explore how sets define a collection with no duplicates, use add and remove to modify them, convert lists to sets to remove duplicates, and examine frozensets as immutable alternatives.

Expose Python comparison operators for numeric and string comparisons, including greater than, less than, equal, not equal, and type differences. Demonstrate logic with and, or, not for complex conditions.

Define a boolean condition with if statements to display messages based on a rating, using elif and else for multiple branches, and print outcomes like excellent, good, or bad course.

Learn to use for loops with range and print, including else blocks, then explore nested loops and while loops with user input and exit conditions.

Define and call functions with def, pass parameters and arguments, and use keyword arguments for readability. Return values versus print-only functions enable reusable code for tasks like emails or databases.

Learn to handle runtime errors with Python exceptions using try, except, else, and finally, and craft friendly error messages for non-integer input. Build robust input handling and multiple exception cases.

Master Python file handling across read, write, and read binary modes; read and write lines; use with open for closing; check file existence with the os module.

Object oriented programming is a programming model organized around data or objects rather than functions and logic. Use classes, objects, attributes, and methods to create instance via constructor in Python.

Learn to organize large Python programs with modules, define functions in separate files, and import them using from module import, import *, or the dot operator to access methods.
