Hi, I'am new to Python - I was practicing some coding and got into error:AttributeError: 'ResturantUI' object has no attribute 'resturant'

Here's the code:

 from tkinter import *
from chapter9 import resturant
class ResturantUI(Frame):
    def __init__(self,master):
        super(ResturantUI, self).__init__(master)
        self.grid()
        self.create_widget()
        self.resturant = resturant.Resturant('item1',2)
        self.resturant.add_item('item2',3)

    def create_widget(self):
        Label(self,text="ResturantUI").grid(row=0,column=0,columnspan=1,sticky=W)
        Label(text="Here's the menu!...").grid(row=1,column=0,columnspan=3,sticky=W)
        Entry(text=self.resturant.__str__(self)).grid(row=2,column=1,columnspan=3,sticky=W)
root = Tk()
root.title('REsturantUI')
root.geometry('200x100')
app = ResturantUI(root)
root.mainloop() 

# Following is the code of resturant

class Resturant():
    def __init__(self,item,price):
        # dictionary to store item and price
        self.d = {}

        self.item = item
        self.price = price
        self.d[item] = price

    def __str__(self):
        rep = ""
        if self.d.items():
            for item in self.d.keys():
                rep += item +':\t'+str(self.d[item])+'\n'
            if self.total:
                rep += 'Your bill is: '+str(self.total)
            return rep
        else:
            rep = "<EMPTY>"
            return rep
    def add_item(self,item,price):
        self.d.__setitem__(item,price)

    def remove_item(self,item):
        if self.d.__contains__(item):
            self.d.pop(item)
    @property
    def total(self):
        amount = 0
        for k in self.d.keys():
            amount += self.d.get(k)
        return amount 

THIS IS THE ERROR AM FACING..
Entry(text=self.resturant.__str__(self)).grid(row=2,column=1,columnspan=3,sticky=W)
AttributeError: 'ResturantUI' object has no attribute 'resturant'

create_widget in which is using self.resturant is before the creation of self.resturant. Switch them around.

        self.resturant = resturant.Resturant('item1',2)
        self.resturant.add_item('item2',3)
        self.create_widget()

Hi, Thanks for your response, It worked. My bad didn't see how I declared the statements.
