Gabriel, Thank you. This makes sense to me. I will go with sys.modules. Can you give me a good example how to do it getattr way?
currently I am having this problem in my code. Kinda off subject, but not entirely. I set default variable in self.opt after that I import jar.properties into self.opt['properties']. Now my self.opt doesn't have the same defaults set. in other words we load our configuration properties. Then we over write any configuration properties with supplied sys.argv[1::] arguments I am passing my sys.argv to a class and inside the class I use getopt to get site_name and files_name, also many other variable that overwrite the configuration that is set from the jar.properties This was working when I was using exec and eval. I was not able to just use exec I had to use exec on import and eval on module.module it was wierd, can someone tell me why? -Alex Goretoy http://www.goretoy.com On Thu, Mar 12, 2009 at 1:00 PM, Gabriel Genellina <gagsl-...@yahoo.com.ar>wrote: > En Thu, 12 Mar 2009 09:27:35 -0200, alex goretoy < > aleksandr.gore...@gmail.com> escribió: > > note i would still like to be able to do __import__("sys")."path" >>> >> > p = __import__("sys").path > > That's a convoluted way of doing: > > import sys > p = sys.path > > (except that the latter one inserts "sys" in the current namespace) > > maybe if __import__ had __str__ defined, How is my thinking on this? >>> and how would I achieve something like this? >>> >> > __str__ has absolutely nothing to do. > > __import__(opt['imp_mod']).options >> >> eval(opt['imp_mod']+"."+opt['imp_opt']) >> >> how to make top work like bottom? >> > > If you think you have to use eval: you don't.
