Python tcl is not installed properly

Question

I just installed graphics.py for python. But when I tried to run the following code:

    from graphics import *

    def main():
        win = GraphWin("My Circle", 100, 100)
        c = Circle(Point(50,50), 10)
        c.draw(win)
        win.getMouse() # Pause to view result
        win.close()    # Close window when done

    main()

my interpreter gave me this strange information:

Traceback (most recent call last):

"uplevel #0 [list source $tclfile]"

This probably means that Tcl wasn't installed properly.

What does it mean? What can I do?

PS: I am using Eclipse (PyDev) for coding.

I sloved by modifying my activate script:

set "TCL_LIBRARY=D:\Program Files (x86)\Python3.5\tcl\tcl8.6"
set "TK_LIBRARY=D:\Program Files (x86)\Python3.5\tcl\tcl8.6"
