List is mutable, tuple is immutable in Python.
List uses square brackets [], tuple uses parentheses ().
List elements can be changed, added, or removed, tuple elements cannot be changed.
Lists are used for collections of items that may need to be modified, tuples are used for fixed collections of items.
Example: list_example = [1, 2, 3], tuple_example = (4, 5, 6)
Namespace is a way to organize variables and functions in a program to avoid naming conflicts.
Namespace helps in avoiding naming conflicts by providing a unique space for each identifier.
Types of namespaces include global namespace, local namespace, built-in namespace, and module namespace.
Example: In Python, each module has its own namespace where all the variables and functions defined in that module reside.
Multiple inheritance in Python allows a class to inherit attributes and methods from more than one parent class.
Python supports multiple inheritance by allowing a class to inherit from multiple parent classes.
The order of parent classes in the inheritance list matters, as methods are searched for in the order they appear.
Diamond problem can occur in multiple inheritance when two parent classes have a common ancestor cl...

Closure is a function that retains the bindings of the free variables that exist when the function is defined.
Closure allows a function to access and manipulate variables outside of its scope.
It is commonly used in callback functions, event handlers, and decorators.
Example: defining a function within another function to access the outer function's variables.

Questions on OOPs concepts, differences between list and tuple, and updating a dictionary.

A set is an unordered collection of unique elements in Python.
Sets are created using curly braces or the set() function.
Sets do not allow duplicate elements.
Sets can perform mathematical operations like union, intersection, difference, and symmetric difference.
Sets are mutable, meaning you can add or remove elements from a set.
Sets are useful for removing duplicates from a list or checking for membership of an element.
Lists are mutable while tuples are immutable.
Lists are enclosed in square brackets [], while tuples are enclosed in parentheses ().
Elements in a list can be added, removed or modified, while elements in a tuple cannot be modified.
Lists are used for collections of homogeneous items, while tuples are used for collections of heterogeneous items.
Lists are generally used for sequences that need to be modified frequently, wh...
