python configparser to parse the data saved in a text file

Question

I have a text file called sampl1.txt. This is what is inside this text file:-

I have a .ini file called config_num.ini which contains:-

[num_group]
file = sample1.txt

Here is the code snippet:-

import ConfigParser
config = ConfigParser.ConfigParser()

config.read('config_num.ini')
sample = config.get('num_group','file')
print sample

Is there any way to parse this so that when I read this 'file' and try to print it, it prints the elements which are in the txt file? Right now it prints sample1.txt. I want the numbers to printed.

does the content of config_num.ini stay the same? – user2963623 Jul 01 '14 at 07:34 — user2963623, Jul 01 '14 at 07:34
yes the content stays the same in .ini file – sam Jul 01 '14 at 07:37 — sam, Jul 01 '14 at 07:37

You almost answered the question in itself!

import ConfigParser
config = ConfigParser.ConfigParser()

config.read('config_num.ini')
sample = config.get('num_group','file')
sample = open(sample, 'r').read()
print sample

Well, you'd have to override your ConfigParser, but I'd advise only loading the file when you call get

from ConfigParser import ConfigParser

class MyConfigParser(ConfigParser):
    def get(self, section, option, **kwargs):
        ret = super(MyConfigParser, self).get(section, option, **kwargs)

        if option == "file":
            try:
                return open(ret, 'r').read()
            except IOError:
                pass

        return ret

Then you can create your new ConfigParser

cfg = MyConfigParser()
cfg.read('config_num.ini')
print cfg.get('num_group', 'file')
