Simple Calculator Python Project

Here is an example of a simple Python project that uses the Tkinter library for GUI:

The project is a simple calculator that can perform basic mathematical operations such as addition, subtraction, multiplication, and division. The calculator has a GUI that is created using the Tkinter library.

Here is an example of the Python code that can be used to create the calculator:

import tkinter as tk class Calculator(tk.Tk): def __init__(self): super().__init__() self.title("Calculator") self.geometry("250x350") self.result = tk.Entry(self, width=35, borderwidth=5) self.result.grid(row=0, column=0, columnspan=4, padx=10, pady=10) self.create_button("1", 1, 1) self.create_button("2", 1, 2) self.create_button("3", 1, 3) self.create_button("4", 2, 1) self.create_button("5", 2, 2) self.create_button("6", 2, 3) self.create_button("7", 3, 1) self.create_button("8", 3, 2) self.create_button("9", 3, 3) self.create_button(".", 4, 1) self.create_button("0", 4, 2) self.create_button("C", 4, 3, command=self.clear) self.create_button("+", 5, 1, command=lambda: self.button_click("+")) self.create_button("-", 5, 2, command=lambda: self.button_click("-")) self.create_button("*", 5, 3, command=lambda: self.button_click("*")) self.create_button("/", 6, 1, command=lambda: self.button_click("/")) self.create_button("=", 6, 2, 3, command=self.equal) def create_button(self, text, row, column, width=1, command=lambda: self.button_click(text)): button = tk.Button(self, text=text, padx=40, pady=20, command=command) button.grid(row=row, column=column, columnspan=width) def button_click(self, text): self.result.insert(tk.END, text) def clear(self): self.result.delete(0, tk.END) def equal(self): try: self.result.delete(0, tk.END) self.result.insert(tk.END, eval(self.result.get())) except: self.result.delete(0, tk.END) self.result.insert(tk.END, "Error") calc = Calculator() calc.mainloop()

This code creates a GUI window using the Tkinter library, and creates a class called "Calculator" that inherits from the Tkinter class "Tk". The class creates a window with a Entry widget where the user can input.
