Learn Python - Full Course for Beginners [Tutorial]

TL;DR

A complete beginner's guide covering Python installation, core concepts, and fundamental programming skills needed to start writing real Python programs.

Key Points

• 1.Why Python: Most in-demand programming language for jobs, automation, and scripting — with near-zero learning curve
• 2.Python 2 vs 3: Always choose Python 3 — it's actively maintained; Python 2 is legacy and dying
• 3.Installation: Download Python 3 from python.org, install PyCharm Community (free) as your IDE
• 4.First Program: Use `print("Hello World")` — output appears in the console below your editor
• 5.How Python Executes Code: Reads and runs instructions top-to-bottom, in order — order matters
• 6.Variables: Named containers storing data (e.g., `character_name = "John"`) — change once, updates everywhere
• 7.3 Core Data Types: Strings (text), Numbers (integers/decimals), Booleans (True/False)
• 8.String Basics: Use quotes to create strings; `\n` adds new lines; `\"` escapes quotation marks
• 9.String Functions: `.lower()`, `.upper()`, `.isupper()`, `.len()`, `.replace()`, `.index()` — all built-in
• 10.String Indexing: Characters accessed by position starting at 0, not 1
• 11.Number Operations: Supports `+`, `-`, `*`, `/`, and `%` (modulus returns remainder)
• 12.Order of Operations: Use parentheses to control math execution order
• 13.Number Functions: `abs()`, `pow()`, `max()`, `min()`, `round()` are built-in
• 14.Math Module: Add `from math import *` to unlock `floor()`, `ceil()`, `sqrt()` and more
• 15.User Input: Use `input()` to capture user data, store it in a variable, and use it in your program
