Lambda function is an anonymous function in Python that can take any number of arguments and return a single expression result.

• Lambda functions are defined using the lambda keyword.

• They are commonly used when a small function is needed for a short period of time.

• Lambda functions can be used as arguments in higher-order functions.

• They are often used in functional programming and for writing concise code.

• Example: lambda x, y: x + y defines a lambda function that takes two argum...read more

Lists and tuples are both sequence data types in Python, but they have some key differences.

• Lists are mutable, meaning their elements can be changed, added, or removed.

• Tuples are immutable, meaning their elements cannot be changed once defined.

• Lists are defined using square brackets [], while tuples are defined using parentheses ().

• Lists are typically used for collections of similar items, while tuples are used for heterogeneous data.

• Lists have more built-in methods and are g...read more

Inheritance is a mechanism in Python OOP where a class inherits the properties and methods of another class.

• Inheritance allows code reusability and promotes the concept of hierarchical relationships.

• The class that is inherited from is called the parent class or base class.

• The class that inherits is called the child class or derived class.

• Child classes can access the attributes and methods of the parent class.

• Child classes can also override or extend the functionality of the p...read more

A function is a block of reusable code that performs a specific task.

• Functions help in organizing code and making it more modular.

• They can take input parameters and return output values.

• Functions can be called multiple times from different parts of the program.

• Examples: print(), len(), range().

OOP in Python is a programming paradigm that allows for the creation of objects with properties and methods.

• OOP stands for Object-Oriented Programming.

• In Python, everything is an object.

• Classes are used to define objects and their behavior.

• Encapsulation, inheritance, and polymorphism are key concepts in OOP.

• Objects can have attributes (variables) and methods (functions).

• Example: creating a class 'Car' with attributes like 'color' and methods like 'start_engine'.
