Prompt Title: Python Calculator with GUI

Sure! Here's a step-by-step guide on how to create a simple Python project using basics, OOP, and GUI:

Step 1: Install Required Libraries

Before we start, make sure you have Python 3.x installed on your computer. You will also need to install the tkinter library, which comes pre-installed with Python, and the numpy library, which we will use in our project. You can install numpy using the following command:

Copy code
pip install numpy

Step 2: Create a Class for the Calculator

We will create a class called Calculator to represent our calculator. This class will contain methods for performing basic arithmetic operations such as addition, subtraction, multiplication, and division. We will also define a method for displaying the result of the calculations in the GUI. Here is the code for the Calculator class:

pythonCopy code
class Calculator:
    def __init__(self):
        self.result = 0

    def add(self, x, y):
        self.result = x + y

    def subtract(self, x, y):
        self.result = x - y

    def multiply(self, x, y):
        self.result = x * y

    def divide(self, x, y):
        self.result = x / y

    def display_result(self):
        print("Result: ", self.result)

In the __init__ method, we initialize the result attribute to zero. The add, subtract, multiply, and divide methods take two arguments, perform the corresponding arithmetic operation, and store the result in the result attribute. The display_result method simply prints the result to the console.

Step 3: Create a GUI using Tkinter

We will use the tkinter library to create a simple GUI for our calculator. Here is the code to create a basic GUI:

pythonCopy code
import tkinter as tk

class CalculatorGUI:
    def __init__(self):
        self.root = tk.Tk()
        self.root.title("Calculator")

        self.num1_label = tk.Label(self.root, text="Number 1")
        self.num1_label.grid(row=0, column=0)

        self.num1_entry = tk.Entry(self.root)
        self.num1_entry.grid(row=0, column=1)

        self.num2_label = tk.Label(self.root, text="Number 2")
        self.num2_label.grid(row=1, column=0)

        self.num2_entry = tk.Entry(self.root)
        self.num2_entry.grid(row=1, column=1)

        self.add_button = tk.Button(self.root, text="+", command=self.add)
        self.add_button.grid(row=2, column=0)

        self.subtract_button = tk.Button(self.root, text="-", command=self.subtract)
        self.subtract_button.grid(row=2, column=1)

        self.multiply_button = tk.Button(self.root, text="*", command=self.multiply)
        self.multiply_button.grid(row=3, column=0)

        self.divide_button = tk.Button(self.root, text="/", command=self.divide)
        self.divide_button.grid(row=3, column=1)

        self.result_label = tk.Label(self.root, text="Result:")
        self.result_label.grid(row=4, column=0)

        self.result_entry = tk.Entry(self.root)
        self.result_entry.grid(row=4, column=1)

    def add(self):
        x = float(self.num1_entry.get())
        y = float(self.num2_entry.get())
        calculator.add(x, y)
        self.result_entry.delete(0, tk.END)
        self.result_entry.insert(0, calculator.result)
