I downloaded Python 3.1 yesterday. I can open the Python command line, but when i press IDLE(Python GUI)shortcut no window or program opens.

i typed to command promt C:\Python31\lib\idlelib\idle.py and got an error message. It's too long to write to here, but in the end of it, it said that "This probably means that Tcl wasn't installed properly". What should I do?

[loewis]

What should I do?

Unset the the TCL_LIBRARY and TK_LIBRARY environment variables, and
report whether it helped.

[Estroms]

I'm beginner, so where can I find those things?

[briancurtin]

In a command prompt window, type the following:

C:\>set TCL_LIBRARY=
C:\>set TK_LIBRARY=
C:\>C:\Python31\python.exe C:\Python31\Lib\idlelib\idle.py

[Estroms]

When I write to Command Promt "C:\>set TCL_LIBRARY=" it says: "'C:\' is not recognized as an internal or external command, operable program or batch file."

[briancurtin]

That was an example of the cmd prompt.
Just type "set TCL_LIBRARY=" without the quotes, along with the contents of the other three lines except for the "C:\>".

[Estroms]

When I type "set TCL_LIBRARY" it says "TCL_LIBRARY=C:IBMTOOLS\Python22\tcl\tcl18.4".
So I have older version of python on my computer in IBMtools, but I want to use the new Python. How can I uninstall older python, because it can't be found in Start menu and there is no uninstall program in python folder. So how can I uninstall it using command prompt?

[briancurtin]

Just delete the Python22 folder.

Typing "set TCL_LIBRARY=" (note the equal sign) will unset the environment variable for that command prompt. Can you try running the steps from msg100786?

[loewis]

I recommend against deleting that Python installation: it probably came from the PC vendor, and might serve a purpose.

Just unset TCL_LIBRARY, through the Windows Environment GUI. Ask on comp.lang.python how to do this, or on some Windows help forum.
