Exercício Python #077 - Contando vogais em Tupla

Introduction

In this tutorial, we will create a Python program that counts the vowels in a tuple of words. This exercise is part of a series designed to enhance your Python programming skills, particularly in handling data structures like tuples and strings.

Step 1: Create a Tuple of Words

Start by defining a tuple that contains several words. Remember, the words should not include any accents.

• Open your Python environment (IDLE, Jupyter Notebook, etc.).
• Define a tuple with words. For example:

words = ('banana', 'abacaxi', 'laranja', 'uva', 'manga')

Step 2: Define a Function to Count Vowels

Next, create a function that will iterate over each word in the tuple and count the vowels.

• Define a function called count_vowels.
• Use a for loop to go through each word.
• Inside the loop, create a list to hold the vowels found in each word.

Here’s an example implementation:

def count_vowels(words):
    vowels = 'aeiou'
    for word in words:
        found_vowels = [letter for letter in word if letter in vowels]
        print(f'Vowels in "{word}": {found_vowels}')

Step 3: Call the Function

After defining your function, you need to call it and pass the tuple as an argument.

• Below your function definition, call the function:

count_vowels(words)

Common Pitfalls to Avoid

• Ensure that the words in your tuple do not contain any special characters or accents, as this exercise specifies.
• Double-check your function for syntax errors, especially in the list comprehension.

Practical Tips

• You can modify the tuple to include different words to test the function with various inputs.
• Consider expanding the function to count the frequency of each vowel if you want to add more complexity.

Conclusion

In this tutorial, we created a simple Python program to count vowels in a tuple of words. You learned how to define a tuple, create a function to process the words, and print the vowels for each word. As a next step, try modifying the program to count the frequency of each vowel or include more words in the tuple. Happy coding!
