How do you create a list in Python?

• You create a list in Python using curly braces, e.g., my_list = {1, 2, 3}.

• You create a list in Python using square brackets, e.g., my_list = [1, 2, 3].

• You create a list in Python using parentheses, e.g., my_list = (1, 2, 3).

What is the purpose of the 'if' statement in Python?

• To create a loop that iterates over a list.

• To import modules into a Python script.

• To execute code conditionally based on a boolean expression.

• To define a function in Python.

How do you write a for loop in Python?

• for each item in sequence:

What is the difference between a function and a method in Python?

• A method is always a built-in function, while a function is user-defined.

• Functions and methods are the same and can be used interchangeably in Python.

• A function can only be used within a class, while a method can be used anywhere.

• A function is a standalone block of code, while a method is a function associated with an object.

What is encapsulation in object-oriented programming?

• Encapsulation refers to the inheritance of properties from a parent class.

• Encapsulation is the process of creating multiple instances of a class.

• Encapsulation is the bundling of data and methods that operate on that data, restricting direct access to some of the object's components.

• Encapsulation is the method of exposing all data and methods of an object to the outside world.
