Variables and Data Types

Variables

x = 5          # Integer
y = "Hello"    # String
z = 3.14       # Float
is_true = True # Boolean

Basic Data Types

1. Numbers

   • Integers: 5, -3, 0
   • Floats: 3.14, -0.001

2. Strings

   name = "Alice"
   greeting = 'Hello World'
   

3. Booleans

   is_active = True
   is_admin = False
   

Type Checking

type(5)        # <class 'int'>
type("Hello")  # <class 'str'>
type(True)     # <class 'bool'>

Type Conversion

int("5")      # 5
str(42)       # "42"
float("3.14") # 3.14
