FYI, there is a “parse” library on PyPI: https://pypi.org/project/parse/
*Parse strings using a specification based on the Python format() syntax.*
*parse() is the opposite of format()*

people unfamiliar with regexes or C-s
We've used a lot of boolean environment variables in a recent project I've
been working on, this led us to create a wrapper to os.getenv that
essentially converts the result to a boolean using distutils.util.strtobool
if an optional kwarg to our wrapper is set to True.
Would it be far-fetched to h

We did use distutils.util.strtobool(os.getenv(key, default)) for a while,
eventually we just built a helper that did the same because it's easier /
more comfortable.

Can you elaborate? Here'
There are many times where the variable ultimately isn’t defined by your
software but by someone else’s, in which case something like an empty
string maybe considered true or false (depending of if existence/emptiness
is used for indicating the boolean value). So I think it’s important that
it be

There are a lot of ways to interpret "convert to bool" - should
"yes" and "no" be converted? What about "1" and "0"? Or "001", or
"-1"? What should happen to unrecognised values? What if

I believe that single value has to be either an array or an object. At

But we’ve gotten quite sidetracked :-)
