I am making a calculator and I get TypeError: can only concatenate str (not "int") to str-CodePudding

Here are the codes

from tkinter import *

I receive the error in this part

button_eq = Button(window,photo_eq)

button_mini = Button(window,photo_mini)

button_plus = Button(window,photo_plus)

button_mult = Button(window,photo_mult)

here is the error

How can I correct the error?

CodePudding user response：

As @derek suggested in the comments, you may try button_0 = Button(windows, image=photo_0)

CodePudding user response：

You need to use something like this:

photo_0 = PhotoImage(file="calc.0.png")
button_calc = tk.Button(root, text="ButtonText", image=photo_0 , command=print_hello)
button_calc.pack()

where photo_0 is your image, images and print_hello is the function for button use.
