PART B: PROGRAMMING WITH STRINGS

Develop a Python program which will convert English words into their Pig Latin form, as described below.

$$ You will work with partners on this exercise during your lab session. On$-$line students: you can do

it on your own or with a partner. Best place to find a partner is Piazza.

The program will repeatedly prompt the user to enter a word. First convert the word to lower case. The word

will be converted to Pig Latin using the following rules:

a$)$ If the word begins with a vowel, append $$way$$ to the end of the word.

b$)$ If the word begins with a consonant, remove all consonants from the beginning of the word and

append them to the end of the word. Then, append $$ay$$ to the end of the word.

For example:

"dog" becomes "ogday"

"scratch" becomes "atchscray"

$"$is$"$ becomes "isway"

"apple" becomes "appleway"

"Hello" becomes "ellohay"

$"$a$"$ becomes "away"

The program will halt when the user enters $$quit$($any combination of lower and upper case letters, such as

$$QUIT$,$Quit$$ or $$qUIt$).$

Suggestions:

a$)$ Use $.$lower$()$ to change the word to lower case.

b$)$ How do you find the position of the first vowel? I like using enumerate$($word$)$ as in

for i$,$ch in enumerate$($word$)$

where ch is each character in the word and i is the character$$s index $($position$).$

c$)$ Use slicing to isolate the first letter of each word.

d$)$ Use slicing and concatenation to form the equivalent Pig Latin words.

e$)$ Use the in operator and the string "aeiou" to test for vowels.

Good practice: define a constant VOWELS $=$ "aeiou"
