Homework 8: Fun with Functions and Maps!

Welcome!

Let's practice Python functions by building and exploring a fun 2D map. Each task is broken into easy steps, with hints and examples. You can use code from workshop_7 for help.

1. Create a Pet Park Map

• Write a function to make a 2D grid (list of lists) with any number of rows and columns.
• Each cell should randomly be one of these areas: 'grass', 'pond', 'hill', 'tree'.
• Use emojis for each area: 'grass' = '🟩', 'pond' = '🟦', 'hill' = '🏔️', 'tree' = '🌲'.
• HINT: Use the random module and random.choice().
• Write another function to print the map nicely.
• Example for a 3x3 map:

🟩🟦🌲
🏔️🟩🟩
🟦🌲🟩

• Try changing the size and see what happens!

2. Numeric Map to Emoji Map

• Make a dictionary:

emojis = {
    1: '🟩',  # grass
    2: '🟦',  # pond
    3: '🏔️',  # hill
    4: '🌲'   # tree
}

• Write a function to make a grid with numbers (1-4) instead of emojis.
• Let the user choose the width and height. Example: generate_map(width, height).
• Write a function to turn the number map into an emoji map and print it.
• Example:

game_map = [
    [1, 2, 4],
    [3, 1, 1],
    [2, 4, 1]
]

Prints:

🟩🟦🌲
🏔️🟩🟩
🟦🌲🟩

• HINT: Use loops and the emojis dictionary.

---

3. Find a Type of Area

• Write a function to search the map for a specific number (e.g., 2 for pond).
• Return a list of coordinates (row, column) where you find it.
• Example: Searching for ponds (2) might return: Found pond at: (0, 1), (2, 0)
• HINT: Use nested loops and enumerate().

---

4. Planting Game!

• Make a grid for a farm, with empty cells as '🟫'.
• Let the user "plant" crops (e.g., '🌽' for corn) by entering row and column numbers.
• After each planting, show the updated farm.
• HINT: Use input() and loops.
• Example after planting:

🟫🟫🟫🟫
🟫🌽🌽🟫
🟫🟫🟫🟫
🟫🟫🌽🟫

• Try adding your own crop emoji!

Bonus: Be Creative!

• Add your own area or crop types and emojis.
• Try making a bigger map, or a map with obstacles.
• Share your favorite map with a friend!

Tips

• Use comments to explain your code.
• Test each function with different inputs.
• Ask for help if you get stuck—coding is teamwork!
