My first thought was that this is a job for string.Template, which has
always struck me as subclassing-friendly. Took about a half hour of
wrangling the regex to get here:
from string import Template, _sentinel_dict
class TemplateWithDefaults(Template):

Oh, I didn't even know about `format_map`! Or `__format__` for that matter.
This makes everything much easier. For my purposes, I don't even need to use
`__format__` since I am not using format strings.

you are iterating over in a for loop in the one line containing the for
statement. And that is more or less the principle I tend to follow, unless the
for statement simply gets to be too long. I have even used th
