Drat. It uses (by explicit design) "the standard import mechanism" to
load the module, which means it doesn't work for exactly the thing I'm
trying to do: load a program file *not* named with a '.py' suffix.
I've long been able to load my program modules from no-suffix
filenames (or indeed any non-standard filenames) with this function::
def make_module_from_file(module_name, file_name):
""" Make a new module object from the code in specified file """
from types import ModuleType
module = ModuleType(module_name)
module_file = open(file_name, 'r')
exec module_file in module.__dict__
sys.modules[module_name] = module
return module
Unfortunately, it seems that "module is already present with name
'foo' in 'sys.modules'" is insufficient for the Python import
mechanism. The module loader used by 'runpy' still complains that it
can't find the module, which is no surprise because its filename is
not that of a library module.
Perhaps I need to delve into the details of the import mechanism
myself :-(
