Our code for this example starts by creating an instance of ConfigParser as usual but this time it sets interpolation parameter with an instance of ExtendedInterpolation. This article will show you some examples. vanilla configparser maintainer for CPython and is currently I don't know what the original model for ConfigParser was (aside from a vague wave in the direction of Windows INI files of some vintage; I'm slightly familiar with them from the Win4Workgroups era), or how much variance there might be in later versions of Windows (aside from that note in the docs about the extended form that CP does not support). The only two phases when you should explicitly state encoding Our code for this example starts as usual by creating an instance of ConfigParser. 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. 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. barlist = CONFIG.clear() ConfigParser allows to use interpolation in the configuration file.

Example: @Henry Cooke Have you tested that when a key is listed multiple times? It then writes the contents of the configuration to a file and verifies the contents of the file by printing them at last. First, we add a section with add_section.

Since Python 3.2, we can read configuration data from a string with the strings The only time when you deal with raw bytes is when you write the data to ConfigParser Work with configuration files Use the ConfigParser module to manage user-editable configuration files for an application. Why does the second bowl of popcorn pop better in the microwave? Here section is optional and if we don't specify the section then it'll try to retrieve that value from the key of the current section or default section. @DevPlayer With multi-key usage you only get the last value. This is but they are converted to Unicode for internal storage anyway. To learn more, see our tips on writing great answers. [SECTION] foo = False >>> config['SECTION']['foo'] 'False' key foo the only problem I see is that I need to make an executable out of my script (using cxfreeze).. The code for this example is almost the same as our previous example with a minor change. We found a way for you to contribute to the project! How do I make a flat list out of a list of lists? To read a boolean value, you use: Config.getboolean(section,option) Example, continuing from above: You can also use getint(section,option) to get a number as an int. it won't matter if you pass them as bytestrings or Unicode. configparser is being used within popular public projects. Below, we have listed important sections of tutorial to give an overview of the material covered. One sort would supply default definitions only for substitution; its entries would never be pushed into the sections' namespaces. That means importing configuration from JSON or specifying default We are then treading ConfigParser instance as a dictionary and printing information about a different section. reading/writing files requires encoding your text to bytes. The inclusion of the defaults by the write() method is unfortunate; these were intended to be a way for an application to supply computed values that would be used if a specific configuration did not override them. You can program your collaborating on the project. Our code then parses contents of dictionary into ConfigParser instance using read_dict() method. Webpython configparser conf. json.loads('{"key": "value"}') and not ' (single quotes) or you will get a JSONDecodeError. It then reads the configuration contents from the file which we created in the previous example. import functools storage and reading/writing files.

Please make a note that whenever particular section does not have any key then it'll try to retrieve that key's value from default section. Some people are concerned about using python file as config file (terming it as security hazard, which is somewhat an unfounded fear), but there also this group who believe that users should edit config files a not python files which serve as config file.

There was at the time no need to distinguish between different uses of "default" values, as MartinManey suggests below. characters, the name of the DEFAULT section, the interpolation Between this historical accident and lack of a clear specification of the "INI" format has made this module very tedious to maintain, so the implementation has been changed in almost every Python release, and the behavior of the module has proven very tedious to describe completely. with the upstream implementation in CPython. It has a community of Should additional namespaces ("types of defaults") ever be considered, I'd hope they don't become part of the set of section names by dumb accident.
