_{Project 1 — Step 15 of 16}

⭐ Step 15 — Change the dice

➡️ Use the player’s chosen number of sides for the roll.

Whatever the player types in input(...) comes back as text — even if they type a number. To use it in math, we have to change it into a number using int().

✏️ What to type

Change the roll = ... line to use int(max) instead of 6:

    roll = randint(1, int(max))

# imports
from datetime import datetime
from random import randint

# variables
world = '🌍🌎🌏'
python = 'Python 🐍'
fire = '🔥'

# Function definitions
def roll_dice():
    max = input('How many sides on your dice?:')
    print(f'That is a D {max}')
    roll = randint(1, 6)
    print(f'You rolled a {roll} {fire * roll}')

# Put code to run under here
print(f'Hello {world}')
print(f'Welcome to {python}')
print(f'{python} is good at maths!')
print(f'{111111111 * 111111111}')
print(f'The date and time is {datetime.now()}')
roll_dice()

Tap ▶ Run, type 12 for a 12-sided dice, press Enter. You should see:

That is a D 12
You rolled a 5 🔥🔥🔥🔥🔥

Now the roll can be any number up to what you typed. Try a D100!

🔍 Tip

Changing one kind of data to another (text → number) is called type casting.
