Please do no change the code provided, I get marked off for that.

Instructions 0. Remember to comment. If your code fails to perform the task at hand but your comments are describing proper code execution I can award a substanial amount of points for logical errors in your program. Think of comments as the equivalent of showing your work in a math class. 1. Read all instructions carefully, ask questions if anything is confusing. 2. Fill in the code/text blocks to answer each question. 3. Do not change any of the existing code provided. The code is specifically there to help you! 4. Run the entire notebook before submitting it on Sakai to make sure that the code actually runs without errors 5. Important: Any question for which your code fails to run will receive 0 points. 6. Have fun! 7. DO NOT USE ANY PACKAGES, other than the ones I have imported. Part of learning is to struggle through the "hard way" before getting to do things the easy way. Any packagesI have importe aefair game and you may use any functions unless otherwise specified. If I've imported them after a function, I've deliberately made it so you cannot retroactively use them in an earlier problem. 8. If I've used return(None) for a function, you may definitely change the return type. It's just a placeholder 9. While you may discuss the concepts of the problems with your peers your code will need to be yours and yours alone 10. Replace CS497 with your BUID (ie if I was turning in this assignment my file would be called dbrennan_lab4) Problem 2 (35 points) Write a function vowel_reverser that takes a word (a string) and reverses the vowels. "Hello" becomes "Holle" "butterscotch" becomes "botterscutch". The e didn't switch places with anything If the word contains anything other than letters [A. Za. z] return the empty string. Punctuation, special symbols, hypthens, spaces etc should return the empty string. In [15]: from string import ascii_letters #asciLletters is uppercase + Lowercase combined from string import ascii_letters In [14]: def vowel_reverser(word): output-" return(output) in [ ]: H
