Hi,
I didn't get it to work. Classes and OO in general have always given me
problems. After working with Python a little, I have gotten somewhat
better but not much. I did this in two files to get some practise with
import. Import works fine, but I may have gone about the class thing
completely wrong. My code has changed slightly from what I posted
earlier. So, here's my code for each file:
#dice.py
class dice:
def __init__(self,numDice):
self.numDice = numDice
def roll(self):
import random
die = []
x = 0
while x < self.numDice:
die.append(random.randint(1,6))
x += 1
return die
#dice-test.py
#!/usr/bin/python
import dice
score = 0
roll = dice.dice(1)
cast = roll.roll()
score += int(cast)
print score
