  1. What are Variables? Explain how variables act as containers for storing data values. Show how to declare and use variables in Python with examples: code: #any name you can proceed name = "PythonHub" age = 23 Mention Python's dynamic typing (no need to declare variable types explicitly). 2. Python Data Types   ->String : Used for text (e.g., "Hello, World!" ). Example: code:    greeting = "Hello" print ( type (greeting)) # Output: <class 'str'>   ->Integer: For whole numbers (e.g., 42 ). Example: number = 100 print ( type (number)) # Output: <class 'int'>  ->Float: For decimal numbers (e.g., 3.14 ). Example: pi = 3.14 print ( type (pi)) # Output: <class 'float'>  ->Boolean: For true/false values ( True , False ). Example: is_active = True print(type(is_active))  # Output: <class 'bool'> 3. Type Casting Show how to convert between different data types. Example: age = "16...
