Climate Quest - Task 7

Objectives

  • Define iteration in programming and its importance.
  • Recognize the concept of loops as a fundamental element of iteration.
  • Differentiate between for and while loops in Python.
  • Explain when to use a for loop and when to use a while loop.
  • Describe the purpose of the range() function in for loops.
  • Illustrate the use of for loops to iterate over sequences like lists, tuples, and strings.
  • Explain the concept of nested for loops and demonstrate their use with examples.
  • Understand the structure of a while loop in Python.
  • Compare and contrast for loops and while loops.

Task Overview:

In this homework, you will enhance the "Climate Quest" project by incorporating iteration. You will use for and while loops to handle repeated tasks and processes within the game. This will make the code more efficient and introduce the concept of looping through sequences and repeating actions.

Instructions:

  1. Use for Loops to Iterate Over Sequences:

    • Implement for loops to handle repeated actions in the game, such as iterating over challenges.

  2. Use while Loops for Repeated Actions:

    • Implement while loops for conditions where the repetition depends on a condition, such as continuing the game until a certain condition is met.

  3. Nested for Loops:

    • Use nested for loops where appropriate, for example, when dealing with multiple elements within a challenge.

Detailed Steps:

Experiment with two different approaches to the game:

  • The user visits a predetermined number of locations, say 3, as part of the game
  • The user has to visit all of the locations before being presented with a final challenge

In both instances the main menu will have to be returned to and presented to the user, either for a set number of times, or until all locations have been visited

  1. Use for Loops to Iterate Over Sequences:

    Update the main gameplay loop to use a for loop to iterate over a predefined number of challenges provided by the range() function:

     1
 2
 3
 4
 5
 6
 7
 8
 9

11

    def main():

    # Gameplay Loop
    for _ in range(3):  # Example loop for 3 challenges
        display_menu()
        location = get_valid_input("Choose a challenge (1-6): ")
        if location == 1:
            environment_health = ocean_challenge(environment_health)
        elif location == 2:
            environment_health = forest_challenge(environment_health)
        elif location == 3:
            environment_health = city_challenge(environment_health)
        # etc..
        display_message(f"Updated environmental health: {environment_health}")

    # End Game
    display_message("Thank you for playing Climate Quest!")

  2. Use while Loops for Repeated Actions:

    Repeat the previous exercise but this time using a while loop. For this exercise there will be 2 conditions:

    • while score > 0 and visited_locations < 6:

    Adjust the main() function to display the menu while these two conditions are True.

Example Homework Questions:

  1. Use for Loops to Iterate Over Sequences:

    • Refactor your main gameplay loop to use a for loop to iterate over a predefined number of challenges.

  2. Use while Loops for Repeated Actions:

    • Modify your main gameplay loop to use a while loop to continue the game until the environmental health drops below a certain threshold.
