Class has no attribute <obj-name> - arunprasanth - Mar-17-2019
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.
