面向对象编程中的 tkinter

Question

I am doing OOP code and I have some problem, I have searched the internet and supposedly I am doing it right. But it gives me an error and does not execute me.

I have this:

from tkinter import *
from tkinter import ttk
import pymysql
from tkinter import messagebox as MessageBox
from tkinter import scrolledtext as st

class Aplicacion:
    def __init__(self):
        self.ventana1 = Tk()
        self.ventana1.title("Login")
        self.ventana1.geometry("400x400")
        self.imagenLogo = PhotoImage(file="logo2.png")
        self.divLogo = Label(self.ventana1, image=self.imagenLogo)
        self.divLogo.place(x=93, y=0)
        self.x_ventana = self.ventana1.winfo_screenwidth() // 2 - 300 // 2
        self.y_ventana = self.ventana1.winfo_screenheight() // 2 - 300 // 2
        self.posicion = str(300) + "x" + str(300) + "+" + str(self.x_ventana) + "+" + str(self.y_ventana)
        self.ventana1.geometry(self.posicion)
        self.ventana1.resizable(0,0)
        self.formulario()
        self.ventana1.mainloop()

    def formulario(self):
        ### Formulario de Entrada ###
        self.label1 = ttk.Label(text="Usuario:").place(x=50, y=110)


Ventana = Aplicacion()

What I want is to insert a tkinter Label into the viewport from a function. But it gives me this error in sublime text:

File "/Users/tomas/Downloads/DonMovil/objetos.py", line 29
    self.label1 = ttk.Label(text="Usuario:").place(x=50, y=110)
TabError: inconsistent use of tabs and spaces in indentation

You need to fix indentation by using either 4 spaces or a tab. You can't interchange between them or it won't work. I don't know why but that is the way it is. I recommend shift tabbing them back to start and then using tab until the indentation is right. Get rid of spaces for indentations too. Make sure to research by searching (copying and pasting) the exact error code you got (IE "TabError: inconsistent use of tabs and spaces in indentation") as @Bryan Oakley suggested.
