--description--

Given a string of words, return a new string where each word is replaced by its length.

• Words in the given string will be separated by a single space
• Keep the spaces in the returned string.

For example, given "hello world", return "5 5".

--hints--

convert_words("hello world") should return "5 5".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(convert_words("hello world"), "5 5")`)
}})

convert_words("Thanks and happy coding") should return "6 3 5 6".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(convert_words("Thanks and happy coding"), "6 3 5 6")`)
}})

convert_words("The quick brown fox jumps over the lazy dog") should return "3 5 5 3 5 4 3 4 3".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(convert_words("The quick brown fox jumps over the lazy dog"), "3 5 5 3 5 4 3 4 3")`)
}})

convert_words("Lorem ipsum dolor sit amet consectetur adipiscing elit donec ut ligula vehicula iaculis orci vel semper nisl") should return "5 5 5 3 4 11 10 4 5 2 6 8 7 4 3 6 4".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(convert_words("Lorem ipsum dolor sit amet consectetur adipiscing elit donec ut ligula vehicula iaculis orci vel semper nisl"), "5 5 5 3 4 11 10 4 5 2 6 8 7 4 3 6 4")`)
}})
