I am working with a word which is input by the user. Example: "where". I need to find the first vowel and start the word from it, and place the beginning of the word to the end.

First I want to understand indexes of each letter and I did it with enumerate(): Now I want to get the index of a vowel and make the word sliced.

The question is how to pass to python the information about the indices I got from enumerate and how to make it define the index of the vowel?

I found lots of tutorials on slicing, but still did not get how to unite these two functions. Please help me (maybe you know a tutorial which can help or just give ideas). I am a beginner, so keep it simple, please. I am stuck, I don't understand how to iterate through the word/words and at the same time get its index.

    Please clarify by showing the output you expect and the problem you have with your current code (which you seem to have forgotten to post) – DarkKnight Feb 19 '23 at 08:03

You can use the following:

word = 'where'
i_vowel = 0
for index, char in enumerate(word):
    if char in "aeiou":
        i_vowel = index
        break
word = word[i_vowel:]+word[0:i_vowel]

Use enumerate to "walk" the string. This gives you the index (subscript) and character at the corresponding position. Then a simple slice will give the output you need.

VOWELS = set('aeiouAEIOU')

s = 'where'

for i, c in enumerate(s):
    if c in VOWELS:
        print(f'{s[i:]}{s[:i]}')
        break

Output:

word = 'where'
vowels = "aeiou"

for i, letter in enumerate(word):
    if letter in vowels:
        i_word = word[i:] + word[:i]
        break

print(i_word)
