How to use lambda in Python

This article will explain in detail how to use lambda in Python. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Description

1. Lambda acts as a sketch of the function, allowing you to embed the definition of the function in the code you use, which is optional (you can use def instead).

But when you only need to cut into the executable code, it makes it easier to write.

2. Lambda is usually used to write jump tables, that is, behavior lists or dictionaries, which can be operated as needed.

Example

L = [lambda x: X * * 2, lambda x: X * * 3, lambda x: X * * 4] for f in l: print (f (2)) > > 4 > 8 > 16print (l [0] (3)) > 9 this article on "how to use lambda in Python" ends here.
