Just needs to remember that functions with same name and different parameter's are different In our case is_integer(num): user-defined function #which is defined by us is_integer(): inbuilt function #which is used inside the function I am also following same tutorial in freecodecamp youtube channel, Object oriented programming using python [this video] At 1:09:00 timestamp i faced similar confusion so i ran it is separately and understood it, we are not removing any .0 from num and we are using recursion. the .is_integer() function used inside without parameter is inbuilt function enter link description here [LINK] so that inbuilt function generally removes .0 presence and return true for integer

I try to learn OOP from this video [this video] at 1:30:00 is what related to my question, but in this code snippet, I will delete anything that is unrelate to the question, and the code snippet alone should provide enough context. My parent class has name, price and quantity as the arguments. My child class has a unique argument call "broken_phone". The problem is centering around repr This is the code that was shown in the video(exclude unrelated stuff) class Item: all = [] def __init__(self, name:str , price: float , quantity:int): #Assign to self object self.name = name self.price = price self.quantity = quantity #action to execute Item.all.append(self) def __repr__(self): return f'{self.__cl

Tkinter is based on different progamming language, named tcl and thats why things seem a bit unpythonic here. The tk.Frame object isnt a pure python object, rather its an wrapped object in a tcl interpreter and thats why you cant address the attributes you intuitivly think you can. You need to adress the attributes in a way the tcl interpreter is abel to handle and therefor methods are created like widget.configure . To achive what you want with your current code, it would look like: import tkinter as tk root = tk.Tk() class MyFrame(): def __init__(self, bg_color): self.window = tk.Frame(width=500,height=500,bg=bg_color) frame_obj = MyFrame('blue') frame_obj.window.pack(fill=tk.BOTH) frame_o

I am currently following this tutorial about Object Oriented Programming but even though i followed all the steps i can't seem to find a solutions as to why my code gets this error and i have no clue what this error means, here's the vid to compare if needed: text [this video] I keep getting this error [LINK] here's my code: import csv class Item: pay_rate = 0.8 #the pay rate after 20% discount all = [] def __init__(self, name: str, price: float, quantity = 0): #Run validations to the received arguments assert price >= 0, f"Price {price} is not greater than or equal to zero!" assert quantity >= 0, f"Quantity {quantity} is not greater than or equal to zero" #assign to self object self.name = name
