If you want to literally pass in a list then you can use: ast.literal_eval() The configparser module in Python is used for working with configuration files. As a part of our fifth example, we'll explain how we can add/remove sections/options from the configuration using methods of ConfigParser instance. We are also printing information about each section using items() method. It then creates a dictionary with configuration details. can one turn left and right at a red light with dual lane turns? but they are converted to Unicode for internal storage anyway. Our code for this example starts by creating an instance of ConfigParser as usual. Python has a module named logging that uses configuration files for the configuration of default logging system. Making statements based on opinion; back them up with references or personal experience. it has "--exclude-modules". you pass a bytestring that cannot be converted to Unicode using the Thanks for contributing an answer to Stack Overflow! 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. a file. The project takes the following branching approach: [1] To somewhat ease migration, passing bytestrings is still supported Configuration information pertains to how to initialize some parameters of the software or some properties which are retrieved from these kinds of files. Please make a note that if we set interpolation parameter to None then the special handling of formatted string won't happen. storage and reading/writing files.

You termed this as ugly, but this is a viable solution. It then initializes each section with an empty dictionary. Since Python 3.2, we can read configuration data from a string with the Use Snyk Code to scan source code in Explanation: We first import the configparser, tell it to read the file, and get a listing of the sections. You can freely exchange the data you store between sources. So another way, which I prefer, is to just split the values, for example: #/path/to/config.cfg configuration language for Python programs. predictable for users. How do I iterate through two lists in parallel? Our third option format3 is included to explain how we can escape % character. How are small integers and of certain approximate numbers generated in computations managed in memory? especially powerful when you start interacting with multiple data Without it I should have had to split data that was all very closely related into two separate parts. 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.
