I think setting parameters in a config file and setting them on the
command line both have their merits. I like to combine ConfigObj with
argparse; something like:
#~~~
parser = argparse.ArgumentParser()
cfg = configobj.ConfigObj("params_file.cfg")
parser.set_defaults(**cfg.config)
#~~~
Then call parser.parse_args, which will override parameters in the config
file by specifying values on the command line.

Re: [Numpy-discussion] Reading automatically all the parameters from a file
My suggestion is: don't. It's easier to script runs if you read parameters from the command line. I recommend argparse. Giovanni Plantageneto wrote: > Dear all, > I have a simple question.

I use this module extensively for my simulation configuration. It can even do some validation of parameters and allows for saving of comments. Furthermore, it utilizes the dictionary idiom, which makes it very easy to work with, especially for passing kwargs to functions. Cheers!

I like having my input files simply be python files, on the form
bar = 'foo'
ham = ['spam', 'eggs']
Then I import them as
import imp
parameters = imp.load_source("parameters", "myinpufile.py")
Now the object 'parameters' is a python module so I can say
print parameters.bar
and 'foo' will be printed.

You could just use a dictionary for your params, and import it from your "configuration file". If you insist on an ini format, ConfigParser/configparser looks pretty good. fwiw, Alan Isaac ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

You may want to give something like configobj a try. http://pypi.python.org/pypi/configobj It builds on ConfigParser to read all of the parameters in and creates a hierarchical object will all of the parameters as attributes. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
[Numpy-discussion] Reading automatically all the parameters from a file
Dear all, I have a simple question. I would like to have all the parameters of a model written in a configuration file (text), and I would like to have all the parameters in the file automatically defined inside a program. I find ConfigParser a bit low level, is there any function that automatically reads everything from a file? Thanks. ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
