Fixes #12388

The outer list comprehension could be simplified. Just move the format string to the first arg of self.note.

@97littleleaf11 not sure if I got it correctly.

Is it something like converting below

for line in ['    {}: {}'.format(k, v) for k, v in sorted_locals.items()]:
    self.note(line, context)

to

for k,v in sorted_locals.items():
    self.note('    {}: {}'.format(k, v), context)
