3. (supplemental) Basic use of lambda expressions in Python

Lambda expressions, also known as anonymous functions, are ' mini-editions ' of normal functions

The format of the lambda expression:

Lambda parameter: An expression

Func1 = Lambda x:x+1

Func1 (10)

>>>11

As can be seen from the above example, the lambda function does not need to manually define the return value, and the result of the expression is returned directly as the return value.

For example, define a lambda function that adds a bitch string to the front of each string.

Func2 = lambda name: "Bitch" + Name

Print Func2 ("Jolin")

>>>bitch Jolin
