I'm starting to build an application for automated network troubleshooting. It's going without any issues so far. I'm using an OOP approach @ which i create the widgets in the init method. what's bothering me is that when the application starts getting more complex (Ex: Adding way more widgets); the init method will get more crowded limiting the visibility of the code.

Is there a better way to create the widgets without crowding the init() method?

from tkinter import *
import customtkinter

class App(customtkinter.CTk):
    def __init__(self):
        super().__init__()

        self.title("Automated TShooting Application")
        self.geometry("587x450+500+50")
        self.iconbitmap("Sharingan.ico")
        self.resizable(False, False)

        self.mainframe = customtkinter.CTkFrame(self, width=400, height=400)
        self.mainframe.grid(row=0, column=0, padx=20, pady=(20, 20))

        self.username_label = customtkinter.CTkLabel(self.mainframe, text="Username")
        self.username_label.grid(row=0, column=0, padx=20, pady=(20, 0))
        self.username_entry = customtkinter.CTkEntry(self.mainframe)
        self.username_entry.grid(row=1, column=0, padx=20)

        self.password_label = customtkinter.CTkLabel(self.mainframe, text="Password")
        self.password_label.grid(row=2, column=0)
        self.password_entry = customtkinter.CTkEntry(self.mainframe)
        self.password_entry.grid(row=3, column=0, padx=20, pady=(0, 20))

    

if __name__ == "__main__":
    customtkinter.set_appearance_mode("light")

    app = App()
    app.mainloop()'''
