Solution

The correct answer is lambda.

In Python, anonymous functions—also known as lambda functions—are created using the lambda keyword. These functions can take any number of arguments but only have a single expression. The main advantage of using lambda functions is that they allow for the quick creation of functions that can be defined inline without needing to formally define a function using the def keyword.

For example, a lambda function that adds two numbers can be defined as follows:

add = lambda x, y: x + y

You can then call add(2, 3), and it will return 5. These functions are particularly useful in functional programming constructs, such as being used as an argument to functions like map(), filter(), and reduce(), where a small function is briefly required for a specific operation.
