1. The Vowel Counter (String Analysis)

Instead of just checking for one character (like the "!" in the previous suggestion), in this task you should look for several specific characters.

• The Task: Ask the user to type a sentence. The program should loop through the sentence and count how many vowels (a, e, i, o, u) are in it.
• Concepts: for loops, if statements with multiple conditions (or), and "accumulator" variables (e.g., count = count + 1).
• The "Aha!" Moment: Realizing that a string is just a collection of characters you can inspect one by one.

2. Rock, Paper, Scissors (Logic & Comparison)

This is the ultimate test of if/elif/else logic. It doesn't require complex loops, but it requires "nested" logic (if inside an if).

• The Task:

1. Player inputs "rock", "paper", or "scissors".
2. Computer picks one randomly.
3. Use if statements to determine the winner.

• Concepts: Random selection, comparing strings, handling a "Tie" vs. "Win" vs. "Loss."
• The "Aha!" Moment: Seeing how many different outcomes need to be accounted for in a simple game.

3. The "Even-Odd" Sum (Looping with Math)

This moves away from strings and focuses on the relationship between loops and numbers.

• The Task: Ask the user for a number (e.g., 20). The program should loop from 1 to that number and:

• Print whether each number is "Even" or "Odd".

• At the very end, print the sum of all the even numbers it found.

• Concepts: range(), the modulo operator % (to check for even numbers), and keeping a running total.

• The "Aha!" Moment: Using a loop to do math that would be tedious to do by hand.
