Hi,
Thanks, that seems to be what I was missing. I'm having some further
related trouble though. I want to do something like this:
MODULES = [ 'module1', 'module2' ]
def libinfo():
for m in MODULES:
__import__('libinfo.'+m)
m.libinfo()
CFLAGS+=m.CFLAGS
Here's what you are missing:
__import__ is a _function_ that returns a _module_ (which you are
ignoring in the code above).
A better implementation is:
def libinfo():
for modulename in MODULES:
module = __import__('libinfo.' + modulename)
module.libinfo()
CFLAGS += module.CFLAGS
The module returned by __import__ is _not_ recorded in sys.modules, so
if you have a chance of getting to modules more than once, you might
think about recording it there. Otherwise, you will wind up in the
confusing state of having two of the "same" modules in your address
space.
So, an even better implementation might be:
import sys
def libinfo():
for modulename in MODULES:
fullname = 'libinfo.' + modulename
module = __import__(fullname)
sys.modules[fullname] = module
module.libinfo()
CFLAGS += module.CFLAGS
Remember, this is computer science, not mathematics. We are allowed to
use more than a single (possibly strangely drawn) character per name.
