How to Split Strings into Substrings of Consecutive Vowels in Python

When working with strings in Python, you might find yourself needing to extract specific patterns. One interesting challenge is identifying and isolating substrings formed by consecutive vowels. This could be important for various applications, such as text analysis or linguistic studies. In this post, we'll delve into a straightforward approach to solve this problem without using regular expressions (regex).

Understanding the Problem

The task is to take a long string of letters and find the longest substring of consecutive vowels. For example, given the input string "ultrarevolutionariees", our goal is to identify the longest sequence of vowels and return its length, which in this case is 3 (from "aie").

A Step-by-Step Solution

Let's break down the solution into clear sections using a simple for loop. This will allow us to keep track of consecutive vowels without the complexity of regex.

1. Define the Function

Start by defining a function called solve. This function will take a string as an argument. We’ll also need to store some temporary variables to keep our results.

2. Loop Through Each Letter

Next, we will loop through each character (letter) in the provided string:

Inside this loop, we will check whether the current letter is a vowel.

3. Check if Character is a Vowel

If the character is a vowel (it exists in our vowels string), we append it to our current_sub variable. If it's not a vowel (meaning we've hit a consonant), we'll store the current substring and reset it:

4. Handle the Last Substring

After the loop ends, we should ensure any remaining substring of vowels is added to our list:

5. Calculate Lengths and Return the Maximum

Finally, we'll compute the lengths of all the substrings collected, and return the maximum value found:

Putting it all together, our complete function looks like this:

Conclusion

This straightforward approach allows you to efficiently find the longest substring of consecutive vowels in a given string without diving into regex. With just a simple for loop and some conditional checks, you can achieve the desired result. The beauty of programming often lies in finding simplicity in solutions that initially seem complex.

Give this function a try with different input strings, and see how it performs in various scenarios. Happy coding!
