IN PYTHON

1) Pig Latin

Write a function called igpay(word) that takes in a string word representing a word in English, and returns the word translated into Pig Latin. Pig Latin is a “language” in which English words are translated according to the following rules:

• For any word that begins with one or more consonants: move the consonants to the end of the word and append the string ‘ay’.

• For all other words, append the string ‘way’ to the end.

• For the above you can assume that ‘a’, ‘e’, ‘i’, ‘o’, and ‘u’ are vowels, and any other letter is a consonant. This does mean that ‘y’ is considered a consonant even in situations where it really shouldn’t be.

For this exercise, you can assume the following:

• There will be no punctuation.

• All letters will be lowercase

• Every word will have at least one vowel (so we won’t give you a word like “by”)

Write a helper function that finds the index of the first vowel in a given word, and use that in your main function.

Hints:

• To find the index of the first vowel in a given word, since you’re interested in the indexes, looping through the indexes of the string using range, or enumerate, or a while loop may work better than a direct for loop on the characters.

• Use slicing to break up the string into all of the letters before the vowel, and all of the letters from the vowel onwards.

Examples:

>>> igpay('can')

'ancay'

>>> igpay('answer')

'answerway'

>>> igpay('prepare')

'eparepray'

>>> igpay('synthesis')

'esissynthay'

CODE:

def first_vowel(word):                   # A HELPER FUNCTION WHICH RETURNS THE INDEX OF FIRST VOWEL IN THE WORD
    vowels = "aeiou"                     # STORED THE VOWELS IN A STRING VARIABLE VOWELS
    for index,value in enumerate(word):  # ENUMERATE FUNCTION DOES THE INDEXING FOR THE WORD, FOR EX. ENUMERATE("HELLO") = [(0, 'H'), (1, 'e'), (2, 'l'), (3, 'l'), (4, 'o')] MEANS THE FIRST VALUE IS INDEX AND 2ND VALUE IS THE VALUE AT THAT INDEX
        
        if value in vowels:              # CHECK IF VALUE IS IN VOWELS, THEN RETURN INDEX ELSE DO NOTHING, IN LAST IF VOWEL NOT FOUND RETURN -1 
            return index
    return -1


def igpay(word):                        # FUNCTION WHICH RETURNS THE STRING TRANSLATED TO PIG LATIN
    index = first_vowel(word)           # FIND THE INDEX OF FIRST VOWEL
    
    res = ""                            # INITIALIZE THE RESULTANT STRING RES WITH EMPTY STRING
    
    if index>0:                         # IF INDEX IS GREATER THAN 0 THAT MEANS WORD START WITH A CONSONANT
        
        res+=word[index:]+word[:index]+"ay" # ASSIGN ALL THE LETTERS FROM INDEX TO LAST, AND CONCATENATE AFTER START TO INDEX AND IN LAST AY
        
    elif index==0:                      # IF INDEX IS 0 THAT MEANS WORD STARTS WITH A VOWEL
        res+=word+"way"                 # SO JUST CONCATENATE WAY IN THE LAST OF THE WORD
        
    return res                           # RETURN THE RESULTANT STRING

# SAMPLE INPUT      
print(igpay('can'))
print(igpay('answer'))
print(igpay('prepare'))
print(igpay('synthesis'))

OUTPUT:

ancay
answerway
eparepray
esissynthay
