A function without any name is called an anonymous function. It is also known as lambda function or lambda expression.
An anonymous function can take a number of arguments but can only have one expression.
One is free to use lambda functions wherever function objects are required.
We use lambda functions when we require a nameless function for a short period of time.
lambda argument: expression
f=lambda a: a*a result =f(5) print(result)
This is all about anonymous function in python.
