Question: 
Write a function to find number of even elements in the given list using lambda function.


Model's Code:
def count_even(lst):
    return len(list(filter(lambda x: x % 2 == 0, lst)))



Sample Correct Code:
def count_even(array_nums):
   count_even = len(list(filter(lambda x: (x%2 == 0) , array_nums)))
   return count_even


Asserts:
assert count_even([1, 2, 3, 5, 7, 8, 9, 10])==3
assert count_even([10,15,14,13,-18,12,-20])==5
assert count_even([1, 2, 4, 8, 9])==3
