English to Pig Latin Translator

Pig latin has two very simple rules:

1. If a word starts with a consonant move the first letter(s) of the word, till you reach a vowel, to the end of the word and add "ay" to the end.
   • have ➞ avehay
   • cram ➞ amcray
   • take ➞ aketay
   • cat ➞ atcay
   • shrimp ➞ impshray
   • trebuchet ➞ ebuchettray
2. If a word starts with a vowel add "yay" to the end of the word.
   • ate ➞ ateyay
   • apple ➞ appleyay
   • oaken ➞ oakenyay
   • eagle ➞ eagleyay

Write two functions to make an English to pig latin translator. The first function translate_word(word) takes a single word and returns that word translated into pig latin. The second function translate_sentence(sentence) takes an English sentence and returns that sentence translated into pig latin.

Examples

translate_word("flag") ➞ "agflay"

translate_word("Apple") ➞ "Appleyay"

translate_word("button") ➞ "uttonbay"

translate_word("") ➞ ""

translate_sentence("I like to eat honey waffles.") ➞ "Iyay ikelay otay eatyay oneyhay afflesway."

translate_sentence("Do you think it is going to rain today?") ➞ "Oday ouyay inkthay ityay isyay oinggay otay ainray odaytay?"

Notes

• Regular expressions will help you not mess up the punctuation in the sentence.
• If the original word or sentence starts with a capital letter, the translation should preserve its case (see examples #2, #5 and #6).
