Inheritance is a mechanism in object-oriented programming where a new class is created from an existing class.

• Allows for code reuse and avoids redundancy

• The new class (subclass) inherits properties and methods from the existing class (superclass)

• Subclass can add new properties and methods or override existing ones

• Example: A Car class can inherit properties and methods from a Vehicle class

Lambda functions are anonymous functions that can be defined without a name.

• Lambda functions are defined using the lambda keyword.

• They can take any number of arguments, but can only have one expression.

• They are often used as arguments for higher-order functions.

• Example: lambda x: x**2 defines a lambda function that squares its input.
