Python Lambda anonymous function

One of the most important aspects of Python is functional programming (functional programming), where you can transfer functions where parameters and values are transferred.

Lambda x:x%3 = = 0

and the following equivalence:

def by_three (x):    return x%3 = = 0

We don't need to really give the function a name, it can also work and get the result. This is why the function that lambda creates is an anonymous function.

eg.

My_list = range (+)print filter (lambda x:x% 3 = = 0, my_list)

The result of the operation is:

[0, 3, 6, 9, 12, 15]
