Python filter() Function

Python filter() function is used to get filtered elements. This function takes two arguments, first is a function and the second is iterable. The filter function returns a sequence from those elements of iterable for which function returns True.

The first argument can be None if the function is not available and returns only elements that are True.


  • filter (function, iterable)


function: It is a function. If set to None returns only elements that are True.

Iterable: Any iterable sequence like list, tuple, and string.

Both the parameters are required.


It returns the same as returned by the function.

Let’s see some examples of filter() function to understand it’s functionality.

Python filter() Function Example 1

This simple example returns values higher than 5 using filter function. See the below example.

  • # Python filter() function example
    def filterdata(x):
    if x>5:
    return x
    # Calling function
    result = filter(filterdata,(1,2,6))
    # Displaying result


  • [6]

Python filter() Function Example 2

This function takes the first argument as a function and if no function is passed. It requires None to pass which returns all the True values. See the example below.

  • # Python filter() function example
    # Calling function
    result = filter(None,(1,0,6)) # returns all non-zero values
    result2 = filter(None,(1,0,False,True)) # returns all non-zero and True values
    # Displaying result
    result = list(result)
    result2 = list(result2)


  • [1, 6]
    [1, True]

Python filter() Function Example 3

  • # Python filter() function example
    def mulof3(val):
    if val%3==0:
    return val
    # Calling function
    result = filter(mulof3,(1,3,5,6,8,9,12,14))
    # Displaying result
    result = list(result)
    print(result) # multiples of 3


  • [3, 6, 9, 12]

I got my training from Zeblearn in the Python Certification Training, I would like to say that say he is one of the best trainers. He has not even trained me but also motivated me to explore more and the way he executed the project, in the end, was mind-blowing.
