## The challenge

What if we need the length of the words separated by a space to be added at the end of that same word and have it returned as an array?

 ``````1 2 `````` ``````add_length('apple ban') => ["apple 5", "ban 3"] add_length('you will win') => ["you 3", "will 4", "win 3"] ``````

Your task is to write a function that takes a String and returns an Array/list with the length of each word added to each element.

Note: String will have at least one element; words will always be separated by a space.

## The solution in Python code

Option 1:

 ``````1 2 `````` ``````def add_length(str_): return [str(x)+' '+str(len(x)) for x in str_.split(' ')] ``````

Option 2:

 ``````1 2 `````` ``````def add_length(string): return ["{} {}".format(word, len(word)) for word in string.split(" ")] ``````

Option 3:

 ``````1 2 3 4 5 `````` ``````def add_length(str_): answer = [] for word in str_.split(): answer.append(word + ' ' + str(len(word))) return answer ``````

## Test cases to validate our solution

 ``````1 2 3 4 5 6 7 8 9 `````` ``````import test from solution import add_length @test.describe("Fixed Tests") def basic_tests(): test.assert_equals(add_length('apple ban'),["apple 5", "ban 3"]) test.assert_equals(add_length('you will win'),["you 3", "will 4", "win 3"]) test.assert_equals(add_length('you'),["you 3"]) test.assert_equals(add_length('y'),["y 1"]) ``````
