.. invisible-code-block: python
# change to the temp directory
import os
original_dir = os.getcwd()
os.chdir(tempdir.path)
To construct a configuration file using the :mod:`ConfigParser`
module, you would do the following:
.. code-block:: python
from configparser import ConfigParser
config = ConfigParser()
config.add_section('A Section')
config.set('A Section', 'dir', 'frob')
f = open('example.cfg','w')
config.write(f)
f.close()
The generated configuration file will be as follows:
.. topic:: example.cfg
:class: read-file
::
[A Section]
dir = frob
.. config parser writes whitespace at the end, be careful when testing!
.. invisible-code-block: python
# change out again
import os
os.chdir(original_dir)
