In Python, the creation of anonymous functions at runtime is supported using a construct called lambda.
The lambda keyword in Python is used to define anonymous functions, also known as lambda functions. Lambda functions are small, inline functions that can have any number of parameters but can only have one expression. They are often used for short, one-off operations where defining a named function would be overkill. Lambda functions are particularly useful when passing functions as arguments to higher-order functions like map(), filter(), and reduce().
