Explain the difference between a Python list and a tuple, including whether each is mutable or immutable.
Explain the difference between a Python list and a tuple, including whether each is mutable or immutable.
Lists are mutable sequences, meaning their elements can be changed after creation. Tuples are immutable sequences, meaning their elements cannot be changed after creation.
Write a Python if statement to check if a variable age is between 18 and 65 (inclusive) and prints “Eligible” if it is.
Write a Python if statement to check if a variable age is between 18 and 65 (inclusive) and prints “Eligible” if it is.
age = int(input("Enter age:"))
if 18 <= age <= 65:
print("Eligible")
Describe what is meant by 'dynamically typed' in the context of Python.
Describe what is meant by 'dynamically typed' in the context of Python.
Dynamically typed means that you do not need to declare the type of a variable when you create one. The Python interpreter infers the datatype at runtime.

Study Notes
Python Programming Language Overview
- Python is a high-level, interpreted programming language known for its readability and wide range of applications in web development, data science, automation, AI, and more.
Key Features
- Easy to Read & Write: Python's syntax is similar to English, making it simple to learn and use.
- Dynamically Typed: Variable types do not need to be explicitly declared.
- Interpreted Language: Python code is executed line by line, which facilitates easier debugging.
- Object-Oriented & Functional: Supports multiple programming paradigms.
- Large Standard Library: Provides pre-built functions for various common tasks.
Basic Python Concepts
1. Variables & Data Types
- Python supports various data types including:
- Integers (e.g.,
x = 10) - Floats (e.g.,
y = 3.14) - Strings (e.g.,
name = "Garima") - Booleans (e.g.,
is_valid = True)
- Integers (e.g.,
2. Input & Output
- Python allows capturing user input and displaying output.
- Example: Get user input and display a greeting.
3. Conditional Statements (Decision Making)
- Python enables conditional logic using
if,elif, andelsestatements. - Example: Check if a number is positive, zero, or negative.
4. Loops
- Python utilizes loops for repeated execution of a code block.
forloop: Iterates over a sequence (e.g.,range(5)).whileloop: Repeats as long as a condition is true.
5. Functions
- Functions are reusable blocks of code.
- Example: Define a function to greet users.
6. Lists & Tuples
- Lists: Ordered, mutable sequences (can be changed).
- Tuples: Ordered, immutable sequences (cannot be changed).
- Example usage of Lists and Tuples with data.
7. Dictionaries
- Dictionaries store key-value pairs.
- Data is accessed using keys.
- Example of a dictionary with key-value pairs.
