Discord Bot Exercise 2: Dice Roller Bot

Build a dice roller that your Discord bot can use! This is a classic bot command — users type !roll and the bot rolls dice for them.

Your Task

Write three functions that work together to simulate dice rolling.

Function 1: roll_die(sides)

• Takes the number of sides on a die (e.g. 6 for a standard die)
• Returns a random number from 1 to sides
• Use random.randint(1, sides)

Function 2: roll_multiple(sides, count)

• Takes the number of sides and how many dice to roll
• Uses a loop to call roll_die() multiple times
• Returns a list of all the roll results

Function 3: format_rolls(rolls)

• Takes a list of roll results
• Returns a formatted string showing each roll and the total
• Format: Rolls: 3, 5, 1 | Total: 9

Starter Code

import random

def roll_die(sides):
    # Return a random number from 1 to sides
    pass

def roll_multiple(sides, count):
    # Roll the die 'count' times, collect results in a list
    pass

def format_rolls(rolls):
    # Format the rolls nicely: "Rolls: 3, 5, 1 | Total: 9"
    pass

# Test your functions:
random.seed(42)

single = roll_die(6)
print(f"Single roll: {single}")

rolls = roll_multiple(6, 4)
print(f"Multiple rolls: {rolls}")

print(format_rolls([3, 5, 1, 6]))  # Output: Rolls: 3, 5, 1, 6 | Total: 15
print(format_rolls([20]))  # Output: Rolls: 20 | Total: 20

# Final bot message:
random.seed(99)
my_rolls = roll_multiple(20, 3)
print(f"🎲 Dice Bot 🎲")
print(format_rolls(my_rolls))

Expected Output (with seed 42 / 99)

Your exact numbers may differ when you remove the seed, but the format should match:

Single roll: 2
Multiple rolls: [1, 1, 6, 6]
Rolls: 3, 5, 1, 6 | Total: 15
Rolls: 20 | Total: 20
🎲 Dice Bot 🎲
Rolls: 5, 1, 9 | Total: 15

Hints

def roll_die(sides):
    return random.randint(1, sides)

results = []
for i in range(count):
    results.append(roll_die(sides))
return results

roll_str = ", ".join(str(r) for r in rolls)
total = sum(rolls)
return f"Rolls: {roll_str} | Total: {total}"

import random

def roll_die(sides):
    return random.randint(1, sides)

def roll_multiple(sides, count):
    results = []
    for i in range(count):
        results.append(roll_die(sides))
    return results

def format_rolls(rolls):
    roll_str = ", ".join(str(r) for r in rolls)
    total = sum(rolls)
    return f"Rolls: {roll_str} | Total: {total}"

Topics Practiced

• Functions calling functions — roll_multiple calls roll_die
• Importing modules — import random
• Loops — rolling multiple dice with for
• Lists — collecting results with .append()
• String methods — .join() to combine items
• Return values — each function returns something the next one uses
