python configfile parser example

configparser

# because I have to look up the syntax every time:

import configparser

CONFIG_FILENAME = "/path/to/config.file"
# or
# CONFIG_FILENAME = "../relative/path/to/config.file"
# for current dir, just: "config.file"


config = configparser.ConfigParser()
 
_ = config.read(CONFIG_FILENAME)


# then config entries are in:
config[section][key]

# e.g.,

config['db']['host']
