🌱 Junior Track 01 Master Reference

1. Python Fundamentals (Syntax, Variables, Comments & Execution)

1️⃣ Python Syntax & PEP 8 Indentation

Unlike C, Java, or C++, Python enforces clean readability by requiring whitespace indentation to delimit control structures and function bodies.

                    if is_active:

                        print("System operational")  # 4 spaces indentation

2️⃣ Variable Assignment & Type Hints

Variables are references to objects stored in memory. Type hints improve IDE autocompletion and static analysis.

                    x = 10               # Inferred int

                    x = "Now a string"  # Re-bound to string object

                    score: int = 100     # Type hint (PEP 484)

3️⃣ Comments & Docstrings

Use single-line `#` comments for notes and triple-quoted `"""` strings for module and function docstrings.

                    # Single line comment

                    """
Multi-line docstring
Explaining function behavior
"""
