Best way to retrieve variable values from a text file?

Question

Referring on this question, I have a similar -but not the same- problem..

On my way, I\'ll have some text file, structured like:

var_a: \'home\'
var_         


        

Answer 1

The other solutions posted here didn't work for me, because:

• i just needed parameters from a file for a normal script
• import * didn't work for me, as i need a way to override them by choosing another file
• Just a file with a dict wasn't fine, as I needed comments in it.

So I ended up using Configparser and globals().update()

Test file:

#File parametertest.cfg:
[Settings]
#Comments are no Problem
test= True
bla= False    #Here neither

#that neither

And that's my demo script:

import ConfigParser

cfg = ConfigParser.RawConfigParser()
cfg.read('parametertest.cfg')       # Read file

#print cfg.getboolean('Settings','bla') # Manual Way to acess them

par=dict(cfg.items("Settings"))
for p in par:
    par[p]=par[p].split("#",1)[0].strip() # To get rid of inline comments

globals().update(par)  #Make them availible globally

print bla

It's just for a file with one section now, but that will be easy to adopt.

Hope it will be helpful for someone :)
