Write a python program to filter list elements between 1 to 20 (both inclusive) which are even numbers? |
|
Answer» This can be done in many WAYS. But the more pythonic WAY of doing this is to use filter and lambda. filter() method takes a function and a sequence. The function should return true or false. It runs a function on each element in the sequence and returns an iterator for the elements for which the function returns true. We can pass a normal function to filter but the more pythonic way of doing it is to pass a lambda. nums = list(range(1, 21)) # Include 20filtered_elements = list(filter(lambda x: (x%2 == 0), nums)) # CONVERT iterator to list |
