What you'll learn
- Navigate, create, modify, and delete files and folders with os, os.path, and pathlib.
- Perform high‑level file operations like copying, moving, and archiving with shutil.
- Handle dates, times, time zones, and scheduling accurately using datetime and time.
- Serialize and deserialize data effortlessly with json and csv.
- Parse, search, and transform text like a pro using re (regular expressions).
- Build lightweight, persistent applications with sqlite3 – no external database needed
- Write cleaner, more Pythonic code by knowing exactly which built‑in tool to use for any task.
- Combine all 10 modules into real‑world projects like file organisers, backup scripts, contact books, and data pipelines.
- Execute external commands and control system processes with subprocess. Use sys to handle command‑line arguments, streams, and interpreter settings.

Requirements
- A computer (Windows, macOS, or Linux) with Python 3.8 or later installed. Basic knowledge of Python syntax (variables, loops, functions, lists, dictionaries).
- A willingness to learn by doing – every lecture includes a hands‑on exercise. No third‑party libraries are needed; everything is in Python’s standard library.
Description
Unlock the full power of Python by truly mastering its 10 most important built‑in libraries! This course dives deep into the standard modules you’ll use in every real‑world project – no third‑party dependencies, just pure Python.
We start with the file system: os, os.path, and pathlib give you total control over files, directories, and paths. Next, shutil makes high‑level file operations a breeze, while datetime and time let you handle dates, timestamps, and scheduling accurately. You’ll then learn to serialize and exchange data effortlessly with json and csv, and become a text‑processing ninja with re (regular expressions).
The course then moves to persistence and organisation: sqlite3 brings the power of a relational database to your scripts, while collections and itertools supercharge your data structures and loops. Finally, subprocess and sys give you the tools to interact with the operating system and build robust, production‑ready scripts.
Every module is covered in a dedicated section of 6 lectures, so you’ll get deep, structured knowledge instead of a shallow overview. Each lecture includes a clear explanation, ready‑to‑copy code, pro tips, and a hands‑on exercise with a detailed solution. Plus, detailed voice scripts guide you through every line of code, common mistakes, and real‑world applications, ensuring you truly understand the concepts.
Whether you’re a beginner who wants to build a solid foundation, an intermediate coder looking to fill knowledge gaps, or a professional preparing for interviews, this masterclass will give you the skills to write cleaner, faster, and more Pythonic code. Stop wondering what the standard library can do for you – master it, and become the developer everyone wants on their team.
Who this course is for:
- Python beginners who want to go beyond syntax and understand the standard library deeply.
- Self‑taught programmers who frequently rely on Google or Stack Overflow for basic tasks.
- Intermediate developers who want to write cleaner, faster, and more professional code.
- Students and professionals preparing for coding interviews that test language fundamentals.
- Data analysts and scientists who handle files, text, and data serialisation daily.
