Lists are mutable, ordered collections of items while tuples are immutable, ordered collections of items.
Lists are mutable, meaning their elements can be changed after creation, while tuples are immutable and cannot be changed.
Lists are defined using square brackets [] while tuples are defined using parentheses ().
Lists are typically used for collections of similar items that may need to be modified, while tuples are u...
Python handles conditional statements using if, elif, and else keywords to control the flow of the program.
Python uses if, elif, and else keywords to create conditional statements.
Indentation is crucial in Python to determine the scope of the conditional statements.
Example: if x > 5: print('x is greater than 5')
Example: if x > 5: print('x is greater than 5') elif x == 5: print('x is equal to 5') else: print('x is less
for loop is used for iterating over a sequence while while loop is used for executing a block of code repeatedly as long as a condition is true
For loop is used when the number of iterations is known, while loop is used when the number of iterations is unknown
For loop is more concise and readable for iterating over sequences like lists, while loop is more flexible for complex conditions
Example: for i in range(5): print(...
A function in Python is defined using the 'def' keyword followed by the function name and parameters.
Use the 'def' keyword followed by the function name and parameters enclosed in parentheses.
Indent the function body to define the code block.
Use the 'return' statement to return a value from the function.
Example: def greet(name): print('Hello, ' + name)
Example: def add_numbers(a, b): return a + b
A class is a blueprint for creating objects, while an object is an instance of a class.
A class defines the properties and behaviors that objects of that class will have.
An object is a specific instance of a class, with its own unique data and behavior.
Classes can be thought of as templates, while objects are the actual instances created from those templates.
Example: Class 'Car' defines properties like 'color' and behav...

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...
Lambda function is an anonymous function defined using the lambda keyword in Python.
Lambda functions are used for creating small, one-time use functions without a name.
Syntax: lambda arguments: expression
Example: double = lambda x: x * 2

Tuples in Python are immutable sequences of elements, similar to lists but cannot be changed once created.
Tuples are created using parentheses ()
Elements in a tuple can be of different data types
Tuples are immutable, meaning their elements cannot be changed once created
Tuples can be used as keys in dictionaries
Dict comprehension is a concise way to create dictionaries in Python using a single line of code.
Dict comprehension uses curly braces {} to create a dictionary with key-value pairs.
It can include conditions and loops to filter or modify the elements being added to the dictionary.
Example: {key: value for key, value in iterable if condition}
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.

Python has 35 keywords.
Python has a set of reserved words that cannot be used as variable names or identifiers.
These keywords are used to define the syntax and structure of the Python language.
Examples of Python keywords include 'if', 'else', 'for', 'while', 'def', 'class', 'import', etc.
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...
