Yes.  The * import does not turn method into module functions.


But no, sort of.  MRAB is correct that there is (an undocumented) module 
function by the same name.  It calls tkinter._default_root.tk.mainloop 
if _default_root is not None.  This is true if 
tkinter._support_default_root == 1 (the default, but set to 0 in IDLE) 
and tkinter.Tk has been called at least once.

The function 'mainloop' calls the 'mainloop' method of the root Tk
window created by Tk(), so it does work as-is.


Didn't know that, thank you!

There are a few bits of configuration missing:


--
from tkinter import *

root=Tk()
root.geometry("400x200")


Add:

root.grid_rowconfigure(0, weight=1)
root.grid_columnconfigure(0, weight=1)
root.grid_columnconfigure(1, weight=0)


S=Scrollbar(root)
T=Text(root)
T.grid(row=0,column=0)
S.grid(row=0,column=1)


Change to:

T.grid(row=0, column=0, sticky=NSEW)
S.grid(row=0, column=1, sticky=NS)


S.config(command=T.yview)
T.config(yscrollcommand=S.set)
txt="""This is a very big text

I would like it to work more or less like this

-
from tkinter import *

root=Tk()
root.geometry("400x200")
S=Scrollbar(root)
T=Text(root)
S.pack(side=RIGHT,fill=Y)
T.pack(side=LEFT,fill=Y)
S.config(command=T.yview)
T.config(yscrollcommand=S.set)
txt="""This is a very big text
