Python - Number Divide Error - Solved

[hirushaadi]

NOTE: PROBLEM SOLVED! - i converted the int to a float

 

# i think this code is enough to get what i am saying..
from tkinter import *

window = Tk()

e = Entry(window, width=26, borderwidth=5)
e.grid(row=0, column=0, columnspan=3, padx=10, pady=10)

def button_click(number):
    current = e.get()
    e.delete(0, END)
    e.insert(0, str(current) + str(number))
    
def button_addd():
    first_number = e.get()
    global f_num
    global math
    math = "addition"
    f_num = int(first_number)
    e.delete(0, END)
    
def button_equall():
    second_number = e.get()
    e.delete(0, END)
    if math == "addition":
        e.insert(0, f_num + int(second_number))
    elif math == "substraction":
        e.insert(0, f_num - int(second_number))
    elif math == "multiplication":
        e.insert(0, f_num * int(second_number))
    elif math == "division":
        e.insert(0, f_num / int(second_number))
    elif math == "power":
        e.insert(0, f_num ** int(second_number))
        

button_1 = Button(window, text="1", padx=40, pady=20, command=lambda: button_click(1), bg="#FF5733", fg="#FFFFFF")
button_add = Button(window, text="+", padx=39, pady=20, command=button_addd, bg="#C539B1", fg="#FFFFFF")
button_equal = Button(window, text="=", padx=94, pady=20, command=button_equall, bg="#00f636", fg="#000000")

window.mainloop()

 

all of the code work.. but, i can add one to another number, then add one more to the answer.. but when i use division and then try to add something, some conversion error happens ( i think so )

 

the error i get is 

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\hirusha\AppData\Local\Programs\Python\Python38\lib\tkinter\__init__.py", line 1883, in __call__
    return self.func(*args)
  File "d:/development/Python/Tkinter by codemy/script3.py", line 42, in button_multipyy
    f_num = int(first_number)
ValueError: invalid literal for int() with base 10: '6934088.0'

and i think this is because of the above mentioned reason.. 

 

what can i do?

Use float() instead of int(), if you want to convert decimal-numbers.
