Can I set IDLE to start Python 2.5 by default?

Ok, so I just installed Python 2.7, but I all ready had python 2.5. I realized that because I installed Python 2.7 last, IDLE automatically opens Python 2.7 IDLE, which I don't want. Is there any way to set the Python 2.5 IDLE to automatically open when I use the right click option on a python source file? Thanks.

Solution

  • You can easily create or edit the right-click properties for a file.

    To edit the right-click menu for a particular file extension:

    1. Run assoc .py from the command line and note the name of the association:

      C:>assoc .py
      .py=Python.File

    2. Run regedit.exe.

    3. Browse to HKEY_CLASSES_ROOT\Python.File\shell.
    4. Create a key under shell called Edit with IDLE (or however you want it to show up in the menu).
    5. Create a key under Edit with Idle called command.

    6. Edit the default value to run the command you want. Use "%1" to insert the name of the right-clicked file. Something like:

      c:\python25\pythonw.exe c:\python25\lib\idlelib\idle.pyw "%1"

    Alternatively, just save the following as idle.reg and double-click it to insert this value in the registry.

    Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Python.File\shell\Edit with IDLE\command]
@="\"C:\\Python25\\pythonw.exe\" \"C:\\python25\\Lib\\idlelib\\idle.pyw\" \"%1\""
