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?
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:
def add_length(str_):
return [str(x)+' '+str(len(x)) for x in str_.split(' ')]
Option 2:
def add_length(string):
return ["{} {}".format(word, len(word)) for word in string.split(" ")]
Option 3:
def add_length(str_):
answer = []
for word in str_.split():
answer.append(word + ' ' + str(len(word)))
return answer
Test cases to validate our solution
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"])
