If you get an error message then exit out of Python and call sudo apt-get install python-tk to install it. You can start Python from the command line (with python ) then import Tkinter. It is simple enough to find out (and fix if necessary) though. To install tkinter in Pycharm, install the module “future” and restart pycharm. You don't have a tkinter module like you use while using pip. The name Tkinter comes from Tk interface. Tkinter is included with standard Linux, Microsoft Windows and Mac OS X installs of Python. It is the standard Python interface to the Tk GUI toolkit, and is Python's de facto standard GUI. Tkinter is a Python binding to the Tk GUI toolkit.
