While Python doesn't have a char type (yet), I still find the distinction

The way I tend to use them is that "xxx" is for data
operated on by the program and seen by the user,
and 'xxx' is for things that are only used internally,
e.g. enumerated type values and attribute names for use
by getattr().
I find myself doing something similar. I use '' for anything that is a
dictionary key and "" for things that are strings not meant to be used for
indexing, in particular the things that are looked up. Except when I
don't.
When I am generating HTML using the ll.xist library, which uses constructs
like this:
html.a (u'link text', href="http://url.goes.here/";)
I have just started using '' for text element contents and "" for
attribute values. This way the attribute values (keyword parameters) look
almost the exact same as in actual HTML (only difference is the commas)
(and the escaping), and my editor seems to be designed for C-style
languages where '' are for character constants and "" are for strings so
it highlights them differently.
My personal opinion is that one should not use the different quoting
styles at random, but I am inclined to believe that there is no single
guideline that can apply to everybody.
