Code:

import tkinter

class Car:
    def __init__(self,color,company,model,price,type):
        self.color=color
        self.company=company
        self.model=model
        self.price=price
        self.type=type
    def display_car_setails(self):
        return "A "+self.color+" "+self.company+" car of model "+self.model+". The type of the car is "+self.type+" with price: "+self.price

all_cars=[]
row_number=0
car1=Car("red","BMW","1431","13,00,000","classic")
all_cars.append(car1)
car2=Car("yellow","Audi","14r441","123,00,000","Mountain")
all_cars.append(car2)
car3=Car("blue","Ford","14d2131","19,00,000","VIP")
all_cars.append(car3)
car4=Car("green","Ferrari","3451","243,00,000","Race")
all_cars.append(car4)

def main(all_cars,row_number):
    win=tkinter.Tk()
    tkinter.Label(win,text="List of cars!").grid(row=row_number)
    row_number+=1
    if len(all_cars)!=0:
        for i in range(len(all_cars)):
            tkinter.Label(win,text=all_cars[i].display_car_setails()).grid(row=row_number)
            row_number+=1
    else:
        tkinter.Label(win,text="None").grid(row_number)
        row_number+=1
    win.mainloop()

main(all_cars,row_number)

The above code is a python program contains a Car class. We can add more cars and add in all_cars list. Programs displays all cars in a python GUI.

Pre step to run the program:

Install tkinter in the computer. To install tkinter, run the following command in cmd or terminal.

pip install Tkinter
