LAMDBA-expression

Attention:

1. For handling simple logic

The LAMDBA expression is just an expression, not a block of code, only encapsulates the limited logic, for logically complex code

It is also recommended to use the DEF definition function to handle

2. Auto return

The return statement does not need to be used in the LAMDBA expression, and the result is returned automatically.

Cases:

def func (ARG):
Arg+1
The next two pieces of code function the same
Func = lambda Arg:arg +1

For lamdba expressions for multiple parameters, the example is as follows:
Func = Lambda a,b:a+b

Func = Lambda a,b,**kwargs:a+b
