Coding Challenge: Write a function to count the number of vowels in a given string

Earlier this year, Women Who Code launched its WWCode Days of Code Challenge 2024. Participants could choose challenges ranging from machine learning and mobile to Python, cloud, data, and other emerging technologies.

I enthusiastically joined the Women Who Code Python community for their daily coding challenges. This blog series of mine named, "Coding Challenge" will serve as my documentation and accountability to consistency.

To enhance the experience for all WWCode Days of Code Challenge 2024 participants, I also crafted a nifty "checklist" or tracker. Excited to share that it's already making waves within the community! Check it out here: https://lnkd.in/dPuX7_qc

I've also published an article about Step-by-step guide on how to solve daily coding challenges.

Python Days of Code Challenge - Day 3

How It Works:

• 60 Days, 60 Questions: Dive into daily Python challenges, each marking a step closer to coding mastery. You can start anytime in between as well!

Learning Together:

• Share your solutions, ask questions, and connect with fellow coders in this thread or on social media (Twitter, LinkedIn) - or Github!

• Don't forget to tag us @WWCodePython or use the hashtags #WomenWhoCodePython #PythonDaysofCode so we can celebrate your achievements!

Bonus:

• React to today’s question if you’d like us to solve this LIVE in our upcoming Python Code Jam Sessions

Today's Challenge:

• Write a function to count the number of vowels in a given string

Solution

# Challenge: Write a function to count the number of vowels in a given string

# 1. Understand the Problem
# Inputs: string
# Outputs: integer
# Restrictions:
# - The input should be a string value
# - The output should be a numerical value, the total number of vowels in the given string


# 2. Examples

# Example 1:
# Input: "queue"
# Output: 4

# Example 2:
# Input: "sequoia"
# Output: 5


# 3. Pseudocode

# # Use a list to put all the uppercase and lowercase vowels
# vowels = ["a", "e", "i", "o", "u"]

# # Define the function and name it vowel_counter
# def vowel_counter(given_string):

# # convert the given string to lowercase
#     lowercase_string = given_string.lower()


# # create a variable to initialize count to 0
#     count = 0

# # iterate through each character in the lowercase string
#     for eachChar in lowercase_string:

#     # check if the character is a vowel
#         if eachChar in vowels:

#             # increase the count
#             count = count + 1

# # return the total count
#     return count


# 4. Solve/Simplify

vowels = ["a", "e", "i", "o", "u"]

def vowel_counter(given_string):
    lowercase_string = given_string.lower()

    count = 0
    for eachChar in lowercase_string:
        if eachChar in vowels:
            count = count + 1
    return count


# 5. Refactor or Look Back

# vowels = ["a", "e", "i", "o", "u"]

# def vowel_counter(given_string):
#     lowercase_string = given_string.lower()

#     count = 0
#     for eachChar in lowercase_string:
#         if eachChar in vowels:
#             count += 1
#     return count

# 6. Test the code

print(vowel_counter("queue"))   # Output: 4
print(vowel_counter("sequoia"))  # Output: 5
print(vowel_counter("12345"))  # Output: 0 (no vowels)
