how to maintain tkinter theme when toplevel with different theme is opened

I have tkinter root window and toplevel window with different themes but when i open the toplevel window it changes the root window to the themes set for the toplevel window

I want to maintain the themes set for each window. This results in error _tkinter.TclError: Theme MyStyle already exists when i close the toplevel window and open it again. 

import tkinter as tk
import tkinter.ttk as ttk



def test2():
    rt1 = tk.Toplevel()
    rt1.geometry("500x500")

    s = ttk.Style()
    s.theme_create("MyStyle", parent="alt", settings={
    "TNotebook": {"configure": {"tabmargins": [2, 5, 2, 0]}},
    "TNotebook.Tab": {"configure": {"padding": [50, 8] }}})

    s.theme_use("MyStyle")

    notebook = ttk.Notebook(rt1)

    f1 = tk.Frame(notebook, width=200, height=200)
    f2 = tk.Frame(notebook, width=200, height=200)

    notebook.add(f1, text="tab 1")
    notebook.add(f2, text="tab 2")

    notebook.grid(row=0, column=0, sticky="nw")


root = tk.Tk()
root.geometry("500x500")


tree = ttk.Treeview(root, column=("col1", "col2"))
tree.insert("", tk.END, values=("deee", "fjfj","fjjf", "jfjfjf"))
tree.pack()

b3 = tk.Button(root, text="new", command=test2)
b3.place(x=200, y=200)


root.mainloop()

Right now you are trying to create a style every time the button is pressed and this is what is causing the problem.

Instead just move the theme creation to the the global namespace where it can be created once and it wont be an issue anymore. 

import tkinter as tk
import tkinter.ttk as ttk


def test2():
    rt1 = tk.Toplevel()
    rt1.geometry("500x500")
    notebook = ttk.Notebook(rt1)
    f1 = tk.Frame(notebook, width=200, height=200)
    f2 = tk.Frame(notebook, width=200, height=200)
    notebook.add(f1, text="tab 1")
    notebook.add(f2, text="tab 2")
    notebook.grid(row=0, column=0, sticky="nw")

root = tk.Tk()
root.geometry("500x500")
tree = ttk.Treeview(root, column=("col1", "col2"))
tree.insert("", tk.END, values=("deee", "fjfj","fjjf", "jfjfjf"))
tree.pack()

s = ttk.Style()
s.theme_create("MyStyle", parent="alt", settings={
"TNotebook": {"configure": {"tabmargins": [2, 5, 2, 0]}},
"TNotebook.Tab": {"configure": {"padding": [50, 8] }}})
s.theme_use("MyStyle")

b3 = tk.Button(root, text="new", command=test2)
b3.place(x=200, y=200)
root.mainloop()
