What's wrong with this code?

Activity 2: Find the Pyramid
Randomly place a pyramid (yellow, large turtle) on the screen. Have a second turtle move
randomly until it is close to the pyramid. Stop the seeking turtle once it has found the pyramid.

So here's my code.

from random import*
from turtle graphics*

class pyramid:

pyramid=Turtle()
pyramid.shape("triangle")
pyramid.color("yellow")
pyramid.shapesize(4)
pyramid.up()
pyramid.goto(randint(-300,300), randint(-300,300)
pyramid.down()

class lost_turtle:

lost_turtle=Turtle()
lost_turtle.shape("turtle")
lost_turtle.color("brown")

while (lost_turtle.distance(pyramid)<25):

lost_turtle.fd(randint(10,33))
lost_turtle.rt(randint(0,360))

My teacher said that my while loop does not work because lost_turtle and pyramid only exist in their class and I can't call it. Is there any way to fix this without putting it in one big function or putting it in two files? Help, please!
Also, tell me if you see any general errors. I just started this programming shebang, so don't be too harsh. Thanks

Well, you are not defining your objects properly. You need to read the Python documentation or your course reference material.

Here is a simple class definition:

class Card(object):
    # define class variables, if any
    suitList = ["Hearts", "Diamonds", "Clubs", "Spades"]
    rankList = ["Invalid", "Ace", "2", "3", "4", "5", "6",
                "7", "8", "9", "10", "Jack", "Queen", "King"]
    scoreList = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10]
    # This method is called when the class is called as a function
    def __init__ (self, suit=0, rank=1):
        if suit >= 0 and suit <= 3:
            self.suit = suit
        else:
            self.suit = 0
        if rank >= 1 and rank <= 13:
            self.rank = rank
        else:
            self.rank = 1
        self.score = self.scoreList[self.rank]
        self.cname = self.rankList[self.rank]
        self.sname = self.suitList[self.suit]
    # define your methods and overloads here
    def __str__(self):
        return self.rankList[self.rank] + " of " + self.suitList[self.suit]
 
    def __repr__(self):
        return self.rankList[self.rank] + " of " + self.suitList[self.suit]
 
    def __cmp__(self, other):
        i = cmp(self.rank, other.rank)
        if i == 0:
            return cmp(self.suit, other.suit)
        return i

Some interaction:

>>> Card()
Ace of Hearts
>>> c = Card()
>>> c
Ace of Hearts
>>> str(c)
'Ace of Hearts'
>>> c.rank
1
>>> c.score
1
>>> d = Card(4,5)
>>> d
5 of Hearts
>>> c<d
True
>>> d == c
False
>>> 

Does that help any?

Yeah, I thought that I was doing it wrong. But I'm not sure I understand this. Are you saying that I need to put my classes pyramid and lost_turtles behaviors in a def __init__ function? Sorry, could you explain how I would redifine the classes in my code. Thanks.

Hi ccgrl451

You're so far from the solution, that I'm afraid you need to do this the hard way. Either find a text book, or one of the many web tutorials, or a friend or teacher and prepare for several hours of hard work.

This kind of forum is much more effective when you have specific questions.

Good luck
