# 1. Fill the missing pieces of the count_even_numbers function¶

Fill ____ pieces of the count_even_numbers implemention in order to pass the assertions. You can assume that numbers argument is a list of integers.

In [ ]:
____ count_even_numbers(numbers):
count = 0
for num in ____:
if ____ % 2 == ____:
count += ____
_____ _____

In [ ]:
assert count_even_numbers([1, 2, 3, 4, 5, 6]) == 3
assert count_even_numbers([1, 3, 5, 7]) == 0
assert count_even_numbers([-2, 2, -10, 8]) == 4


# 2. Searching for wanted people¶

Implement find_wanted_people function which takes a list of names (strings) as argument. The function should return a list of names which are present both in WANTED_PEOPLE and in the name list given as argument to the function.

In [ ]:
WANTED_PEOPLE = ['John Doe', 'Clint Eastwood', 'Chuck Norris']

In [ ]:
# Your implementation here

In [ ]:
people_to_check1 = ['Donald Duck', 'Clint Eastwood', 'John Doe', 'Barack Obama']
wanted1 = find_wanted_people(people_to_check1)
assert len(wanted1) == 2
assert 'John Doe' in wanted1
assert 'Clint Eastwood'in wanted1

people_to_check2 = ['Donald Duck', 'Mickey Mouse', 'Zorro', 'Superman', 'Robin Hood']
wanted2 = find_wanted_people(people_to_check2)
assert wanted2 == []


# 3. Counting average length of words in a sentence¶

Create a function average_length_of_words which takes a string as an argument and returns the average length of the words in the string. You can assume that there is a single space between each word and that the input does not have punctuation. The result should be rounded to one decimal place (hint: see round).

In [ ]:
# Your implementation here

In [ ]:
assert average_length_of_words('only four lett erwo rdss') == 4
assert average_length_of_words('one two three') == 3.7
assert average_length_of_words('one two three four') == 3.8
assert average_length_of_words('') == 0
