How to Create Configuration File (*.cfg) Using Python?

The below code help you to create a sample config file using python script. The below code is tested with python 3.4 version:


Step 1:  Check you have python 3.* installed in your machine and also you have python configparser package installed.

Step 2: Create a python file with below scripts, say the python file is saved as CreateConfig.py.

import configparser

config = configparser.RawConfigParser()

#MYSQL_MEL
config.add_section('ETL')
config.set('ETL', 'etldbname', '*****')
config.set('ETL', 'etllogin', '******')
config.set('ETL', 'etlpassword', '****')
config.set('ETL', 'etlport', '****')
config.set('ETL', 'etlserver', '*****')

#FilePath
config.add_section('FPATH')
config.set('FPATH', 'filepath', 'D:/ETLFile/')


# Writing our configuration file to 'ETLConfig.cfg'
with open('ETLConfig.cfg', 'wt') as configfile:
    config.write(configfile)

Step 3: On executing CreateConfig.py file, you can see in your working directory, a new CFG file named ETLConfig.cfg is created with below texts.

[ETL]
etldbname = *****
etllogin = ******
etlpassword = ****
etlport = ****
etlserver = *****

[FPATH]
filepath = D:/ETLFile/

This ETLConfig file can be called in other python files, and the variables can be used as Global Variables in all packages.
