Python Tkinter throwing Tcl error

Question

I am learning basic GUI in Python, and I came across a sample example to read file name from file explorer on Stack Overflow.

from Tkinter import Tk
from tkFileDialog import askopenfilename
Tk().withdraw() # we don't want a full GUI, so keep the root window from appearing
filename = askopenfilename() # show an "Open" dialog box and return the path to the selected file
print(filename)

This particular script is working fine when I am trying to run it in IDLE, but the same is not running if I am trying from command prompt in windows 7.

Python Version: 2.7. Here is the output error which I get.

>>> from Tkinter import Tk
>>> from tkFileDialog import askopenfilename
>>> Tk().withdraw()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\Lib\lib-tk\Tkinter.py", line 1685, in __init__
self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: Can't find a usable init.tcl in the following directories:
C:/Python27/lib/tcl8.5 D:/PyProj/lib/tcl8.5 D:/lib/tcl8.5 D:/PyProj/library D:/library D:/tcl8.5.2/library D:/tcl8.5.2/library

This probably means that Tcl wasn't installed properly

Any pointer to what I am missing here can be of great help.

In case you are using Virtualenv on Windows I found a solution here: https://github.com/pypa/virtualenv/issues/93

I copied the "tcl" folder from C:\Python27\ over to the root of the new Virtualenv, Tkinter.Tk() shows a new window without throwing an exception.

I am running Python 2.7 on Windows 7.

You just need to copy two folders from tcl folder to the Lib folder

tcl8.5 and tk8.5
