Python Lambda Functions: Anonymous Guide

In Python, you can declare anonymous functions using lambda expressions.

The syntax format of a lambda expression is: lambda parameter list: expression

Here is an example:

add = lambda x, y: x + y
print(add(3, 5))  # 输出8

In the above example, an anonymous function called “add” is created using a lambda expression. This function takes two parameters, x and y, and returns their sum. The add function can be directly called to execute it.
