[Python-ideas] String interpolation again.

format = '...{short_descriptive_name}...'
text = format.format(
    short_descriptive_name=long_cumbersome_variable_name,
    other_name=other_name,
    ...)

Don't be afraid of more lines of code if it helps readability.

You could also build a context dict:

context = {}
context['name'] = complicated_code_to_get_name()
...
text = '...{name}...'.format(**context)

Of course personally I want a where/given clause, but that's a different
thread. ;)
