How to use filter, map, and reduce in Python 3

Question

filter, map, and reduce work perfectly in Python 2. Here is an example:

>>> def f(x):
        return x % 2 !=         


        

Answer 1

Since the reduce method has been removed from the built in function from Python3, don't forget to import the functools in your code. Please look at the code snippet below.

import functools
my_list = [10,15,20,25,35]
sum_numbers = functools.reduce(lambda x ,y : x+y , my_list)
print(sum_numbers)
