5. Assignment statement, basic types - int, float, bool - Part A
The chapter discusses the basics of Python programming, particularly focusing on variable assignment, data types, and the proper structuring of code. It emphasizes the importance of defining functions before use and the distinction between integer and floating-point numbers, including how they are represented in memory. The chapter also introduces basic arithmetic operations and highlights Python's flexibility regarding variable types.

What we have learnt
- Python interprets code from top to bottom, with function definitions remembered by the interpreter for later execution.
- The distinction between 'int' and 'float' types in Python affects how numbers are handled and stored in memory.
- Python allows variables to change types dynamically, but it's best practice to keep variable types consistent for code clarity.
Key Concepts
- -- Statement
- The most basic operation in Python where a value is assigned to a variable.
- -- Data Types
- Categories of values in Python, primarily 'int' for integers and 'float' for floating-point numbers.
- -- Arithmetic Operations
- The basic operations that can be performed on numbers, including addition, subtraction, multiplication, and division.
- -- Dynamic Typing
- A feature in Python that allows variables to change types as the program runs.
