Tell us what’s happening:

Stuck on the part “The draw method should behave correctly when the number of balls to extract is bigger than the number of balls in the hat.”

I dont get it, how do I tackle this? My code is given below:

Your code so far

import copy
import random 

class hat:

    def __init__(self,red = None,orange = None,black = None,blue = None,pink = None,striped = None,yellow = None,green = None):

        self.red = red
        self.orange = orange 
        self.black = black
        self.blue = blue 
        self.pink = pink
        self.striped = striped
        self.yellow = yellow 
        self.green = green

        lst = {'red':red,
               'orange':orange,
               'black':black,
               'blue' : blue,
               'pink' : pink,
               'striped' : striped,
               'yellow' : yellow,
               'green' : green
        }

        self.contents = []
        for key,value in lst.items():
            if value is not None :
                self.contents += value*[str(key)]

        self.copy = []
        self.copy = self.contents.copy()

        

    def draw(self,number):

        self.hat_list = []
        self.contents = self.copy.copy()
        
        if number >= len(self.contents) :
                
                self.contents.clear()
                self.hat_list = (self.copy.copy())
    

        else:
                
                for i in range(number):
                     
                     temp = self.contents.index(random.choice(self.contents)) 
                     self.hat_list.append(self.contents.pop(temp))
                     
            
        return self.hat_list

I know that we can use the **kwargs thing in the start to make the code even more efficient. Im just doing it slowly. But im stuck on the third test :frowning:

3

print self.hat_list when the number of balls drawn is greater than the balls it contains. What does it contain?

Hi

Try returning the “self.hat_list” inside the if statement

6

doest seem to work :frowning: using this. Is my logic applied correct?

7

the test that is failing has a color that is not included here, you want to use kwargs like you were saying.

ooooooooooo i seeeeeee thank u! :slight_smile:

THANK YOU SO MUCH. YOU WERE RIGHT AND IT MAKES SENSE!!!

cuz like if the color is any other color not specified then it’ll show wrong on the test

I got it correct now :slight_smile:
I was stuck on this for a day lol

I got the first three correct now. Thanks again

Both your if and else statement should return a list , and inside your “experiment” function make sure you create a copy of the “Hat” object that will be used for drawing random balls

Already resolved, thanks
