Did you intend to make this change? If so, why?

Now that the error message has more than just the key repr in it, I use assertIn to ensure that the error message __contains__ the repr of missing.

Using
os.environ[KEY]with a non-existent environment variable key only gave a simple KeyError, so now, the error message should make more sense when encountered. Obviously, fix my style if it's not up to standard.Linked bugtracker post: https://bugs.python.org/issue44264
