Sets the path to the Python executable to be used for a particular instance.
pithon.set.executable( path.to.python.executable, instance.name="" )
path to the Python executable that should be used.
if specified, use the Python instance with this name
Sets the path to the Python executable to be used for a particular instance. This function must be used before that instance is started, so before using any other function that specifies the instance's name. Otherwise, it will have no further effect.
If the function is not called, the program that has been set using the
pithon.set.defaut.executable function (either explicitly or it's default value)
will be executed and communicated with.
