'Tk' is not defined

Question

I am new to Python. I downloaded Spyder 2.3.1 and am running Python 2.7 on my Mac. I tried this sample program:

from Tkinter import *
root = Tk()

w = Label(root, text="Hello, world!")
w.pack()

root.mainloop()

When I run, I get the error message:

NameError: name 'Tk' is not defined

If I look in the file Tkinter.py, it has the following lines of code:

from Tkinter import *
root = Tk()

w = Label(root, text="Hello, world!")
w.pack()

root.mainloop()

Looks like an infinite loop, but what it is complaining about is "Tk" saying "name not defined". Any help would be greatly appreciated.

p.s. I tried python -m idlelib.idle in a Terminal window and got the error NameError: name 'Tk' is not defined

The filename Tkinter.py prevent the import of the standard library module Tkinter.

Rename the file with different name. Also you shouold remove Tkinter.pyc if there it is.

one more question. I see files open in Spyder that are in the folder path /Users/Ameade/.spyder2/My_Amazing_Script.py - but I don't see a folder called ".spyder2" anywhere. Can you tell me where this is? – user3229570 Oct 26 '14 at 15:30
@user3229570, In Unix sytem, the filename starts with a dot `.` is hidden. You can see the file with command likes `ls -a`. If you don't use command line, check your file browser's option to show hidden files/directories. – falsetru Oct 26 '14 at 15:45
Thanks. I was able to navigate there using the Go menu. I think I will just move these files to another folder. – user3229570 Oct 26 '14 at 15:47
