[Tkinter] Class with text widget method

[Windspar]

1. text_box need to be part of the class. don't make a new one each time method is called.
put in __init__

self.text_box = Text(self.root, bg = 'blue', fg = 'white')
self.text_box.pack(side=LEFT)

here another example

import tkinter as tk

# just inherit it to make custom tk.Text
class Custom_Console(tk.Text):
    def __init__(self, master):
        tk.Text.__init__(self, master, bg = 'blue', fg = 'white')
        self.pack(side = tk.LEFT)

    #custom methods
    def write(self, content):
        self.insert(tk.END, content)

    def writeln(self, content):
        self.insert(tk.END, content + '\n')

def main():
    root = tk.Tk()
    app = Custom_Console(root)
    app.insert(tk.END, "0 ")
    app.write("1 ")
    app.writeln("2")
    app.writeln("Here we go")
    app.mainloop()

if __name__ == '__main__':
    main()
