programiz / calculator Goto Github PK

I am using python3 --version 3.10.6 and tkinter --version 3.8.
I executed a few lines of code:

import tkinter as tk


class Calculator:
    def __int__(self):
        self.window = tk.Tk()
        self.window.geometry("363x497")
        self.window.resizable(0, 0)
        self.window.title("Calculator App")

    def run(self):
        self.window.mainloop()


if __name__ == "__main__":
    calc = Calculator()
    calc.run()

But I got this error:

Traceback (most recent call last):
  File "/home/bhatti/Documents/Programming/Tkinter GUI Calculator/calculator.py", line 17, in <module>
    calc.run()
  File "/home/bhatti/Documents/Programming/Tkinter GUI Calculator/calculator.py", line 12, in run
    self.window.mainloop()
AttributeError: 'Calculator' object has no attribute 'window'

Process finished with exit code 1

Hello, good afternoon. I was looking through all the calculator tutorials, and then I found your video on YouTube. I love your content, but I see a little mistake on line 113 and line 122
This is line 113:
113 self.current_expression = str(eval(f"{self.current_expression}**2"))
Line 113 must be:
self.current_expression = str(eval(f"{float(self.current_expression) ** 2}"))
This is line 122:
self.current_expression = str(eval(f"{self.current_expression}**0.5"))
Line 122 must be
self.current_expression = str(eval(f"{float(self.current_expression) ** 0.5}"))

Or else I think it will produce a SyntaxError. Anyway, you have one of the best calculator apps. 99/100!
