--description--

Given a sentence, return a version of it that sounds like advice from a wise teacher using the following rules:

• Words are separated by a single space.
• Find the first occurrence of one of the following words in the sentence: "have", "must", "are", "will", "can".
• Move all words before and including that word to the end of the sentence and:
  • Preserve the order of the words when you move them.
  • Make them all lowercase.
  • And add a comma and space before them.
• Capitalize the first letter of the new first word of the sentence.
• All given sentences will end with a single punctuation mark. Keep the original punctuation of the sentence and move it to the end of the new sentence.
• Return the new sentence, make sure there's a single space between each word and no spaces at the beginning or end of the sentence.

For example, given "You must speak wisely." return "Speak wisely, you must."

--hints--

wise_speak("You must speak wisely.") should return "Speak wisely, you must."

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(wise_speak("You must speak wisely."), "Speak wisely, you must.")`)
}})

wise_speak("You can do it!") should return "Do it, you can!"

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(wise_speak("You can do it!"), "Do it, you can!")`)
}})

wise_speak("Do you think you will complete this?") should return "Complete this, do you think you will?"

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(wise_speak("Do you think you will complete this?"), "Complete this, do you think you will?")`)
}})

wise_speak("All your base are belong to us.") should return "Belong to us, all your base are."

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(wise_speak("All your base are belong to us."), "Belong to us, all your base are.")`)
}})

wise_speak("You have much to learn.") should return "Much to learn, you have."

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(wise_speak("You have much to learn."), "Much to learn, you have.")`)
}})
