...The repository organizes lessons into numbered folders that progress from basic concepts to advanced language features. Early material covers variables, data types, input, strings, conditions, loops, functions, and common collections. Intermediate lessons explore exceptions, modules, file I/O, functional programming, and extensive object-oriented programming concepts. Later days introduce command-line utilities, generators, regular expressions, AsyncIO, multithreading, and multiprocessing. Exercises and solution days are distributed throughout the sequence so learners can repeatedly apply what they have studied.
