Strange, isn't it ?
Nope. As other said, 'import tkinter as tk' imports a module named
'tkinter' and *in the importing modules, and only in the importing
module*, binds the module to 'tk'. It also caches the module in
sys.modules under its real name, 'tkinter'.
>>> import tkinter as tk
>>> import sys
>>> 'tkinter' in sys.modules
True
>>> 'tk' in sys.modules
False
'import tk.ttk' looks for 'tk' in sys.modules, does not find it, looks
for a module named 'tk' on disk, does not find it, and says so.
