2. Very Short Answer (VSA).

Q1. What is a variable in Python?

Answer: A variable is a named location in memory used to store data. In Python, variables are created when a value is assigned to a name.

Q2. What does the input() function do in Python?

Answer: The input() function in Python reads a line of text from the user as a string via the keyboard.

Q3. Name any two mutable data types in Python.

Answer: List and Dictionary are two mutable data types in Python; they can be changed after creation.

Q4. What symbol is used to start a comment in Python?

Answer: The hash symbol # is used to begin a comment in Python.

Q5. Which operator is used for exponentiation in Python?

Answer: The double asterisk ** is used as the exponentiation operator in Python.

3. Short Answer Questions.

Q1. Explain the difference between interactive mode and script mode in Python.

Answer: In interactive mode, you type and execute one statement at a time, and the result is shown instantly, but code is not saved. In script mode, code is written and saved in a .py file and can be executed as a whole, preserving the script for future use.

Q2. How can you convert a string input from the user into an integer in Python?

Answer: To convert a string input from the user into an integer, use input() to get the value and int() to cast it. For example: age = int(input("Enter your age:")). The int() function converts the input string to an integer type.

Q3. List any two features that make Python a user-friendly programming language.

Answer: Python has a simple and clear syntax, which makes code easy to read and write. It is also portable and platform-independent, allowing programs to run on various operating systems without modification.

Q4. What is debugging? Name two types of errors one can encounter while writing Python programs.

Answer: Debugging is the process of finding and correcting mistakes (bugs) in a program. Two common types of errors in Python are syntax errors (violations of language rules) and runtime errors (errors occurring during execution, like division by zero).

Q5. Why is Python called a high-level language?

Answer: Python is called a high-level language because its syntax is closer to natural language and abstracts away most hardware details, making it easier for humans to code, understand, and maintain programs compared to low-level languages.

4. Long Answer Questions.

Q1. Explain the main data types available in Python with examples.

Answer: Python supports several built-in data types. Integer (int) contains whole numbers, e.g., 5; floating point (float) holds real numbers, e.g., 5.5; Boolean (bool) has values True/False; String (str) stores text, like "Hello"; List (list) and Tuple (tuple) are collections, with lists being mutable and tuples immutable; Set (set) contains unique unordered items; Dictionary (dict) stores key-value pairs, e.g., {'a':1}. Each type serves a special use in Python programming.

1. int: x = 10
2. float: pi = 3.14
3. bool: flag = True
4. str: name = "Ravi"
5. list: nums = [1, 2, 3]
6. tuple: t = (4, 5, 6)
7. set: s = {2, 3, 3}
8. dict: d = {'fruit':'Apple'}

Q2. Discuss the types of operators available in Python and give an example for each type.

Answer: Python includes arithmetic operators (like +, -, *, /), relational operators (==, !=, <, >), assignment operators (=, +=), logical operators (and, or, not), identity operators (is, is not), and membership operators (in, not in). Each serves a specific role; for example, arithmetic operators perform calculations and logical operators manage conditions.

1. Arithmetic: 4 + 5 = 9
2. Relational: 5 == 5 (True)
3. Assignment: x += 2
4. Logical: x > 0 and y < 0
5. Identity: a is b
6. Membership: 3 in [1,2,3]

Q3. Describe with proper examples the difference between explicit and implicit type conversion in Python.

Answer: In explicit type conversion, the programmer intentionally changes a variable's data type (type casting), for example: str(n). In implicit conversion, Python automatically changes the data type when evaluating an expression, such as when adding int and float, the result is float. Both methods ensure variables or results get the correct type for an operation.

1. Explicit: total = str(25+45)
2. Implicit: sum1 = 10 + 20.0 (sum1 is float)

Q4. True or False Questions.

Q1. Python programs are case-sensitive.

Answer: True.

Q2. List data type in Python is immutable.

Answer: False.

Q3. The output of 4 // 2 is 2.0.

Answer: False.

Q4. The keyword 'return' can be used as an identifier.

Answer: False.

5. Match the Following Questions.

Q1. Match the following.

Answer: 1 - A, 2 - B, 3 - C, 4 - D
