为什么我不能在Python中使用ttk？

Question

When I type from Tkinter import ttk it says that there is no module named ttk , and also on many websites online the t in tkinter is always lowercase , but when I type tkinter in Python it throws an error. Why is that?

Answer 1

There is nothing wrong with the case. As other answer specified - its Tkinter in Python 2.x and tkinter in Python 3.x version.

In addition ttk was a separate module in Python 2.x and its a submodule of Tkinter in Python 3.x

So in Python 2.x you would import ttk as

from Tkinter import *
import ttk

And in Python 3.x you would import ttk as

from tkinter import *
from tkinter.ttk import *

or

from tkinter import ttk

Answer 2

python 2.6中的Tkinter是大写的，在python 3中它是小写的， tkinter

Answer 3

To use ttk from Python, you need a separate download and install which you can find here .

Python is case-sensitive (like most programming languages), but "many websites" are not (like most human beings) so it's a perfectly understandable sloppiness on those "many websites"' part to spell Tkinter in the wrong case. Hey, you yourself break English rules by using lower case in words starting sentences, twice in your short question, you should sympathize with the use of wrong casing in those "many websites", and definitely shouldn't be surprised by it!

Answer 4

I have met the same question with you.The fact is in Python2.x, the way to import module is type capitalized "T" in "tkinter":

import Tkinter as tk

And to import "ttk",you can type this:

import ttk

It seems like it is no obvious defferrence of module tkinter in py2.x and py3.x,so just go ahead to use it!good luck!
