I've just started with Python myself and, oddly enough, was having trouble with this very example in Lutz and Ascher.   I downloaded and installed Tcl/Tk 8.3, modified my Autoexec file and restarted, went into the Python shell, and the book example worked with no hitches.   I run Win 98 and had to add the statements below to my Autoexec.bat file (Note that I chose to install Python in C:\Program Files\Python20 instead of the installation default C:\Python20 directory): set PYTHONPATH=C:\Program Files\Python20\Lib;C:\Program Files\Python20\Lib\lib-tk;C:\Program Files\Python20\DLLs set TCL_LIBRARY=C:\Program Files\Tcl\lib\tcl8.3 set TK_LIBRARY=C:\Program Files\Tcl\lib\tk8.3 set path=C:\WINDOWS;C:\WINDOWS\COMMAND;C:\Progra~1\Python20;C:\PROGRA~1\TCL\bin     Fred Hansen Hendersonville, NC
