In this Python lecture, we will learn about the filter function.

"Filter is a function that takes a function and a sequence as a parameter. And returns the elements on which function is true".

Filter( ) in Python

Let's see the example filter function

list(filter(lambda num:num>0,range(-5,5)))

>>[1,2,3,4]

In the above example, filter function is used to grab the elements, greater than zero.

list(filter(lambda num:num%2==0,[0,1,2,3,4,5]))

>>[0,2,4]

In the above example, filter function is used to grab the elements, divisible by zero.
