The module was originally written to support a variant syntax in which the contents of each section resembled RFC 822 headers; the implementation still allows named values to be specified using either syntax. We then load configuration details using read_string() method passing configuration as a single string to it. It'll treat them as simple strings. (NOT interested in AI answers, please). The same desire to keep related data together in the absence of some good reason not to would make it desirable to have this as another magic section. As a part of our fourth example, we'll explain different methods of ConfigParser instance that can be used to parse the contents of a configuration file. Webconfigparser comes from Python 3 and as such it works well with Unicode. Same goes for copying data from another I am not sure if a python module (residing in the same folder as the executable) would work in that case? The sections We can notice that all 4 values required by format1 key are present in that section. The library is generally cleaned up in terms of internal data and from How can I drop 15 V down to 3.7 V to drive a motor? To use the backport instead of the built-in and also you can use json file behind your config file like this: An improvement on split(',') might be to treat the comma separated values as a record in a CSV file. This class lets us specify formatted strings like BasicInterpolation but it also lets us retrieve value from keys of other sections unlike BasicInterpolation which lets us retrieve values only from the current or default section. This allows you to pythonically specify list item datatypes. (I.e., if the system .ini sets a value in the "MyApp" section, but a user .ini sets it in the "Defaults" section, which wins?). What are possible reasons a sound may be continually clicking (low amplitude, no sudden changes in amplitude), What PHILOSOPHERS understand for intelligence? How do I iterate through two lists in parallel? It was in the course of revising this same app that I encountered some cases where I should have liked to have had a DEFINE magic section: one whose values were only used in substitutions in the normal sections, not directly injected into them like DEFAULT. Get notified if your application is affected. I would like to use a dynamically-loaded code module as a configuration file. found. Getting key with maximum value in dictionary? I landed here seeking to consume this [global] Our code for this example starts by creating an instance of ConfigParser as usual. The first section is generally the default section storing default values. But you can still subclass it to check for. The example reads the values and prints them.

For example: The value of config.get('hello','barlist') will now be: Which you easily can split with the splitlines method (don't forget to filter empty items). It uses the % syntax. CONFIG.write(fp) As a part of our second example, we demonstrate how we can read the existing configuration file and print the contents. 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. See the full import os Thanks for contributing an answer to Stack Overflow! How to read a file line-by-line into a list?
