#python #tkinter #import

I don't get the processes behind "import" and "from xyz import". When I code:

from tkinter import *

then I import, I thought, the whole tkinter names into my namespace. But I can't use neither

tkinter.messagebox.showinfo("title", "someinfo")
nor
messagebox.showinfo(...)

To use that, I have to

from tkinter import messagebox

to access it. the same with

import tkinter as tk

... there is no:

tk.messagebox.showinfo...

@fatrat from … import * doesn’t import everything. The module’s author can decide what’s included.

But note that it’s generally considered bad practice to use from … import * as it dumps lots of stuff into the main namespace. It is safer to keep namespaces separate
