I have actually highlighted a small neat recipe for doing such
unpacking, that I use for parsing arbitrary parameters in Evoque
Templating. I never needed to handle "callable" parameters though, as
you do in your 3rd string example, so the little "unpack_symbol"
recipe I have publiched earlier does

Hello,
I'd like to split a string by commas, but only at the "top level" so
to speak. An element can be a comma-less substring, or a
quoted string, or a substring which looks like a function call.
If some element contains commas, I don't want to split it.
Examples:
'foo, bar, baz' => 'foo' 'bar'

Sadly, that is the case. Well, kinda. I'm using psycopg2 to access
postgresql, which is great. Though postgres has more features than
psycopg2 support

Could you please explain which part of my example doesn't work?
split takes arguments which enables it to split your string as
desired.

Thanks Mr. Edwards, I went ahead and started using the csv reader.

The basic split/strip method wouldn't split '(a, b, "c,...", d)',
which is why I chose not to use it.
The csv solution seems to work well, that helped me much here (thank
you), but I am looking to see if I can get it solved with some regular
expression. This is how far I've come so far, but it nee

Hi,
I need to convert the string: '(a, b, "c", d, "e")' into the following
list ['a', 'b', 'c', 'd', 'e']. Much like a csv reader does. I usually
use the split function, but this mini-monster wouldn't properly get
split up due to those random quotations postgresql returns to me.
