> Are there any advantages of YAML over TOML YAML is older and more well supported. I'll explain to you why I ended up choosing YAML for the config files for a CLI utility written in Python that I maintain. I initially chose TOML for many of the reasons mentioned here but before my first release I ended up switching to YAML. Python added support for reading TOML to the standard library in version 3.11, however it still requires you use an external library for writing. Do I use the built in library for reading and an external library for writing? A chunk of my users are on versions of Python older than 3.11 (generally Windows users who installed Python manually at some point), do I import a separate library for THEM to read the files but use the standard library if ver >= 3.11? Now that I look at the state of things today I probably would add the tomlkit library to my setup file, but that wasn't very mature at the time, so I just used pyyaml. Changing it now would break compatibility with my older versions that use yaml config files, unless I maintained both paths... which I could do but it's just another source of complexity to worry about. These are relatively simple config files the user has to interact with manually so yaml works fine and I don't see any reason to change at this point.
