Time for another simple exercise to be solved both in Python and JavaScript!
Here is what I got from ChatGPT:
Exercise: Count Vowels
Write a program that counts the number of vowels in a given string. For this exercise, consider the vowels to be a, e, i, o, and u (you can choose to include or exclude y). The program should take a string as input and output the count of vowels in the string.
For example:
- Given the string
"hello world", the program should output3(since there are three vowels:e,o,o).
This exercise will help you practice string manipulation, looping, and conditionals in both Python and JavaScript.
Here's a breakdown of the task:
- Iterate over each character in the string.
- Check if the character is a vowel.
- Keep a count of the number of vowels.
- Output the final count.
Remember, the logic will be similar in both languages, but the syntax will differ. Give it a try, and see how you can implement this in both Python and JavaScript.
My Code
Alright, let’s give this a try and get started with Python!
# Exercise: Count Vowels
def main():
user_input = input('Input: ')
print(f'Vowels: {countVowels(user_input)}')
def countVowels(string):
count = 0
vowels = "aeiou"
for letter in string:
if letter.lower() in vowels:
count += 1
return count
if __name__ == '__main__':
main()
Alright, here I knew how to make the for loop, just had to ask for help with how to check if the individual letters are vowels. Thought I need some special method or library but turns out I can simply define vowels = "aeiou" and then compare it to that. brilliant!
Now JavaScript, this is going to be more difficult for me.
let user_input = 'Hello World';
for (letter in user_input){
console.log(letter);
}
I tried to start with this. Already doesn’t work because it just gives me numbers instead of the letters. Turns out it can be fixed like this:
let user_input = 'Hello World';
for (let letter of user_input) {
console.log(letter);
}
And then again got some help from ChatGPT for the include(). can’t just use in like in Python before. also .lower() in Python is .toLocaleLowerCase() in JavaScript.
const user_input = prompt("Input: ");
console.log(`Input: ${user_input}`);
const vowels = 'aeiou';
let count = 0;
for (let letter of user_input) {
if (vowels.includes(letter.toLocaleLowerCase())) {
count++;
}
}
console.log(`Vowels: ${count}`);
And then finally I asked chatGPT to put the whole thing in the browser because I wanted to see how that would work.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Vowel Counter</title>
</head>
<body>
<input type="text" id="userInput" placeholder="Type a string">
<button onclick="countVowels()">Count Vowels</button>
<p id="result"></p>
<script>
function countVowels() {
const userInput = document.getElementById('userInput').value;
const vowels = 'aeiou';
let count = 0;
for (let letter of userInput) {
if (vowels.includes(letter.toLowerCase())) {
count++;
}
}
document.getElementById('result').textContent = `Vowels: ${count}`;
}
</script>
</body>
</html>
Pheww sounds like a simple exercise but was a tough one again for me. Will ask for even simpler exercises the next few days!
