The theme is easily installable as a Python package

pip install sv-ttk

Note:

The theme will only be applied to themable (tkinter.ttk) widgets, and not with the regular Tkinter widgets, they only benefit from the colorscheme.

For detailed documentation, visit the wiki page.

import tkinter
from tkinter import ttk

import sv_ttk

root = tkinter.Tk()

button = ttk.Button(root, text="Click me!")
button.pack()

# This is where the magic happens
sv_ttk.set_theme("dark")

root.mainloop()
