commit 9a110c390dce9600ce8323ce8e87b14d379736e4

    Prevent void-variable error in python-mode (bug#73773)
    
    * lisp/progmodes/python.el: Define 'subword-mode' before its use
    in 'python-mode-map' so invoking menu-bar-open in a python-mode
    buffer does not cause a void-variable error when subword-mode is
    not loaded, menu-bar-mode is disabled and debug-on-error is enabled.
