Syntax & Code Structure

Python's syntax enforces clean, readable code by replacing curly braces with structured indentation.

Key Concepts & Detailed Explanation

In Python:

1. 1
   Every indented block starts after a colon (:).
2. 2
   The standard indentation level is 4 spaces. Never mix spaces and tabs.
3. 3
   Python is strictly case-sensitive: 'score', 'Score', and 'SCORE' are 3 different variables.
