"can only concatenate str (not "int") to str"

Question

I’m making a Treasure Island type game using tkinter and trying to increase the font size while having a sort of typerwriter effect that prints out the letters one by one. I’ve gottten them to work by themselves but when I put them both together I get the error "TypeError: can only concatenate str (not "int") to str" in line 39.

code:

import tkinter

window = tkinter.Tk()

window.title("Treasure Island")
window.attributes('-fullscreen', True)

logo = tkinter.Label(window, text='''

logo.pack()
logo.config(font=('length', 15))

line1 = tkinter.Label(window, text="Welcome to Treasure Island,n"
                                   "Your goal is to find the buried Treasure!")

line1.config(font=('length', 15))
label1 = tkinter.StringVar()

a = tkinter.Label(textvariable=label1)

a.pack()
for i in line1:
      a=label1.get()
      label1.set(a+i)
      window.after(50)
      window.update()

space = tkinter.Label(window, text=" n n ")

space.pack()

Answer 1

To get text in your line1 label character by character and show it in sequence, maybe this is what you need

for i in line1.cget("text"):
    a=label1.get()
    label1.set(a+i)
    window.after(50)
    window.update()
