Question 3. Define a function called disemvowel. It should take a single string as its argument. (You can call that argument whatever you want.) It should return a copy of that string, but with all the characters that are vowels removed. (In English, the vowels are the characters "a", "e", "i", "o", and "u".) Hint: To remove all the "a"s from a string, you can use that_string. replace("a", ""). The .replace method for strings returns another string, so you can call replace multiple times, one after the other.
