profig is a straightforward configuration library for Python.



Why another configuration library? The simple answer is that none of the available options give me everything I want, with an API that I enjoy using. This library provides a lot of powerful functionality, but never at the cost of simplicity.


  • Automatic value conversion.
  • Section nesting.
  • Dict-like access.
  • Single-file module with no dependencies.
  • Extensible input/output formats.
  • Built-in support for INI files and the Windows registry.
  • Preserves ordering and comments of INI files.
  • Full Unicode support.
  • Supports Python 2.7+ and 3.2+.


profig installs using easy_install or pip:

$ pip install profig


Basic usage is cake. Let’s assume our config file looks like this:

host =
port = 9090

First, we specify the defaults and types to expect:

>>> cfg = profig.Config('server.cfg')
>>> cfg.init('server.host', 'localhost')
>>> cfg.init('server.port', 8080)

Then, we sync our current state with the state of the config file:

>>> cfg.sync()

As expected, we can access the updated values without undue effort, either directly:

>>> cfg['server.host']

Or by section. Notice that the type of the port option is preserved:

>>> server_cfg = cfg.section('server')
>>> server_cfg['port']
