Q.2. Describe the use of the input() function in Python with an example. Define an identifier and mention the rules for naming identifiers in Python. (10 Marks)

Ans 2.

The input function and identifier naming rules are among the most basic yet important concepts in Python programming. The input function enables interactive programs by accepting user data at runtime. Identifiers are the names assigned to variables, functions, classes, and modules in Python code, and following correct naming rules is essential for writing error-free, readable, and maintainable programs.

The input() Function in Python

The input function pauses program execution and waits for the user to type something and

 

 

Q.3. Explain the difference between break, continue, and pass statements in Python with examples. (10 Marks)

Ans 3.

Python provides three special control flow statements: break, continue, and pass, which modify the normal sequential execution of loops and code blocks. Understanding the precise function and correct usage of each statement is fundamental to writing efficient loop logic, handling edge cases cleanly, and building programs that behave predictably across all input conditions.

The break Statement

Q.4. Differentiate between a Python module and a package. What are the different ways to import a module in Python? Provide examples. (10 Marks)

Ans 4.

Python’s modular design through modules and packages is one of its most powerful organizational features, enabling code reuse, maintainability, and scalability across large software projects. Understanding the distinction between modules and packages and mastering import techniques are fundamental skills for any Python programmer working on real-world applications.

Python Module versus Package

A module in Python is a single file containing Python code, including functions, classes, and

 

 

Q.5. Explain tuples in Python and how they differ from lists in terms of mutability and performance. Also discuss the key characteristics of sets in Python. (10 Marks)

Ans 5.

Python provides multiple built-in data structures for organizing collections of data. Tuples, lists, and sets are three of the most commonly used structures, each with distinct characteristics regarding mutability, ordering, performance, and appropriate use cases. Understanding their differences enables programmers to select the most appropriate structure for each specific programming requirement.

Tuples in Python

A tuple is an ordered, immutable collection of items defined using parentheses. Example:

 

 

Q.6. Discuss the purpose of the try block in Python. Why is the finally block important in a Python program? (10 Marks)

Ans 6.

Exception handling is one of the most important aspects of writing robust, reliable Python programs. The try-except-finally structure provides a systematic mechanism for anticipating, catching, and managing runtime errors without crashing the program. Understanding the specific roles of the try and finally blocks is essential for building production-quality applications that handle errors gracefully and maintain resource integrity.

Purpose of the try Block

The try block contains code that the programmer anticipates might raise an exception during
