loading configuration files that are themselves python

Hi,

Is there a more idiomatic way of loading in a configuration file
that's python code than:

_temp=__import__(path,fromlist='cachestrs')
cachestrs=_temp.cachestrs

? I mean, that's pretty ugly...Plain "import" doesn't work in this
case because 'path' is a variable defined elsewhere

At least you have a way to do it, so you should be happy !-)

Another solution would be to add the path to sys.path, but it wouldn't
necessarily be the best thing to do here.

execfile(path)

in a module with a fixed name that you can import wherever you need access
to your configuration data?

That looks like what I want, thanks

Is it really a good idea to have a configuration language that’s Turing-
complete?

 

[Jean-Michel Pichavant]

I think not. Configuration files should be read as data; they should be
declarative only, not executable languages. That way, a different
program can read and parse them without having to be a parser for an
entire programming language.

For local non distributed applications, configuration files written in
python are just fine.
