I want to be able to import multiple instances of a module and call
each by a unique name and it doesn't appear at first glance that
either import or __import__ have what I need. I need this because of
computing platform I have developed where users write python scripts
to do some analysis of science problems where they call modules that
have code for monipulating data and where the imported module does
some specific scientfic manipulation of data. The key problem is that
the module might locally store some partial results ready for the
next time its called to save CPU time (typically the results for one
timestep ready for the next timestep). But if the module is called for
two different purposes in two different parts of the script then the
second call will actually see the partial results from the 1st call
and vice versa. The simple solution is if it were possible to import
the same module file twice but for them to act like they were
different modules. It was also make it easy to parallelise code
without the called module needing to be thread safe (each instance
would be one thread) but that is a lesser priority for the moment.
If I have module in a file called stuff.py has in it a global variable
somevariable I want to be able to import multiple instance (with
seperate name spaces etc) of stuff so that I could have for example
a=instance1ofstuff.somevariable
b=instance2ofstuff.somevariable
and a and b are referring to different variables in entirely different
modules. IS there any way to do this?
