Understand Python - Coding

Python Basics

1. Variables - Storing Data

                    name = "Alice"        # String (text)

                    age = 15              # Integer (whole number)

                    height = 1.65         # Float (decimal)

                    is_student = True     # Boolean (True/False)

Rules:

Variable names can contain letters, numbers, underscore
Cannot start with a number
Case-sensitive: age and Age are different

2. Data Types

Type	Example	Description
int	42, -7, 0	Whole numbers
float	3.14, -2.5	Decimal numbers
str	"Hello", 'Python'	Text (strings)
bool	True, False	Boolean values

3. Operators

Operator	Meaning	Example
+	Addition	5 + 3 = 8
-	Subtraction	10 - 4 = 6
*	Multiplication	6 * 7 = 42
/	Division	15 / 3 = 5.0
//	Integer Division	17 // 5 = 3
%	Modulus (remainder)	17 % 5 = 2
**	Exponent (power)	2 ** 3 = 8
