The sections ConfigParser instance, thanks to its mapping protocol support. code : l = config.get('sect', 'alist').split('\n') My experience with this, an app that had a need before I was familiar with ConfigParser, leads me to suggest that whatever abstract elegance there would be in doing away with the magic DEFAULT section, it is in fact very convenient in practice. on Snyk Advisor to see the full health analysis. 20 open source contributors I would like to use a dynamically-loaded code module as a configuration file. For example configuration: [section] Of course the programmatic way of injecting default values (or defined ones, if that were added to the model) has its place as well. We use a wrapper API that takes the section and option names, and searches for a platform-specific value before getting the non-specific value. We are then printing section details to verify that formatted strings were properly interpreted or not. You can Find secure code to use in your application or website. How can I read in lists within a list using ConfigParser() in Python? Depending on the parser's mode, blank you pass a bytestring that cannot be converted to Unicode using the The most obvious one, at least to me, is when the default values should in fact be kept separately from the sections' data, or when they are a way of injecting information from the environment into the config. To learn more, see our tips on writing great answers. For me, this clicks for numbers but as cfg files are mostly editable - adding "" everytime is a pain.

Healthy. Our third option format3 is included to explain how we can escape % character. We have two sections of configuration data. Only This allows you to pythonically specify list item datatypes. (responding to 2 yr old comment for benefit of other readers). Unable to edit the page? json.loads & ast.literal_eval seems to be working but simple list within config is treating each character as byte so returning even square bracket. meaning if config has fieldvalue = [1,2,3,4,5], then config.read(*.cfg) New lines that are items should start with whitespace (e.g. About: Sunny Solanki holds a bachelor's degree in Information Technology (2006-2010) from L.D.
