What are the key components of a Python program?
✔✔The key components of a Python program include variables, data types, control structures,
functions, and input/output operations.
How do you define a function in Python?
✔✔A function in Python is defined using the `def` keyword followed by the function name and
parentheses, with the function body indented underneath.
What is the difference between a list and a tuple in Python?
✔✔The difference between a list and a tuple in Python is that a list is mutable (can be changed),
while a tuple is immutable (cannot be changed after creation).
How do you handle exceptions in Python?
✔✔Exceptions in Python are handled using the `try` and `except` blocks, allowing programmers
to manage errors without crashing the program.
1
,What is the purpose of a loop in programming?
✔✔The purpose of a loop in programming is to execute a block of code repeatedly as long as a
specified condition is true.
What are the two main types of loops in Python?
✔✔The two main types of loops in Python are `for` loops and `while` loops, each serving
different purposes for iteration.
What is the role of conditional statements in programming?
✔✔Conditional statements in programming control the flow of execution based on whether a
specified condition evaluates to true or false.
How can you read user input in a Python program?
✔✔User input in a Python program can be read using the `input()` function, which captures input
as a string from the console.
What is a dictionary in Python, and how is it different from a list?
✔✔A dictionary in Python is a collection of key-value pairs, allowing for fast lookups based on
keys, while a list is an ordered collection indexed by integers.

,What is meant by “scope” in programming?
✔✔Scope in programming refers to the visibility and lifetime of variables, determining where
they can be accessed and modified in the code.
How do you create a class in Python?
✔✔A class in Python is created using the `class` keyword, followed by the class name and a
colon, with the class attributes and methods defined within an indented block.
What is inheritance in object-oriented programming?
✔✔Inheritance in object-oriented programming allows a class to inherit attributes and methods
from another class, promoting code reusability.
What is the purpose of comments in code?
✔✔Comments in code serve to explain and clarify the code's purpose and functionality, making
it easier for others (and the original author) to understand the code later.
How can you import a module in Python?
3
, ✔✔A module in Python can be imported using the `import` statement, followed by the module
name, which allows access to its functions and classes.
What is the difference between `==` and `is` in Python?
✔✔The `==` operator checks for value equality, while the `is` operator checks for object
identity, determining if two references point to the same object in memory.
What are the benefits of using functions in programming?
✔✔The benefits of using functions in programming include code reusability, improved
readability, and easier maintenance by breaking down complex tasks into smaller, manageable
pieces.
What is a syntax error, and how can it be identified?
✔✔A syntax error occurs when the code violates the rules of the programming language, and it
can typically be identified by the interpreter or compiler, which will provide error messages
indicating the issue.
