What is a `list comprehension` in Python, and how is it used?
✔✔ A `list comprehension` in Python is a concise way to create lists using a single line of code.
It allows for the generation of lists by applying an expression to each element in an iterable,
optionally filtering elements based on a condition.
How does a `recursive` function work, and what is its purpose?
✔✔ A `recursive` function is a function that calls itself to solve a problem by breaking it down
into smaller, more manageable sub-problems. It is useful for tasks that can be divided into
similar sub-tasks, such as computing factorials or traversing hierarchical structures.
What is the role of an `algorithm` in data processing?
✔✔ An algorithm provides a step-by-step procedure for performing data processing tasks, such
as sorting or searching. It ensures that data is handled efficiently and correctly, which is crucial
for producing accurate and timely results.

,What does the `modulus operator` do, and how is it used in programming?
✔✔ The `modulus operator` (%) computes the remainder of the division of one number by
another. It is used to determine if a number is divisible by another, to cycle through a range of
values, and in various arithmetic calculations.
How does `decomposition` aid in programming problem-solving?
✔✔ Decomposition involves breaking down a complex problem into smaller, more manageable
parts. This approach makes it easier to understand, design, and implement solutions by focusing
on simpler components individually.
What is the purpose of `pseudo-code`, and how is it utilized in programming?
✔✔ `Pseudo-code` is a simplified, informal way of describing the logic of an algorithm or
program. It is used to outline the steps and flow of a solution in a language-agnostic manner,
making it easier to translate into actual code later.

, What is the concept of `data abstraction`, and how is it implemented?
✔✔ `Data abstraction` involves hiding the complex implementation details of data structures and
exposing only the essential features. It is implemented through abstract data types, encapsulation,
and interfaces to manage and manipulate data more effectively.
How does `event-driven programming` work, and where is it commonly used?
✔✔ `Event-driven programming` is a paradigm where the flow of the program is determined by
events such as user actions, sensor outputs, or messages from other programs. It is commonly
used in graphical user interfaces (GUIs) and interactive applications to respond to user input.
What is a `Boolean expression`, and how is it used in conditional statements?
✔✔ A `Boolean expression` evaluates to either `true` or `false` and is used in conditional
statements to control the flow of execution. It helps determine which block of code should be
executed based on the outcome of the expression.
How do `data structures` like stacks and queues differ from each other?
