getting the following error when I run my code, 'str' object cannot be interpreted as an integer, how can I fix this?

Question

I posted the relevant code as well as the full traceback for the error. I have tried converting different elements to int, but none of that has worked. How can I fix this problem so that my code runs correctly and inserts data from the list into my listbox?

Answer 1

In line 48, you probably meant to write input_list.insert(tk.END, item)

data is a list, its method .insert doesn't work with tk.END (which is the string 'end')

input_list is instead a tkinter.Listbox and its .insert does perfectly fine with it
