ups, didn't know you were ill, but you seem to have fun recovering :-)

Oh, ^^^^ you mean a comma here, i guess?!

actually i'd prefer
assert f(x) + g(x) == q(x), 'Message to print when the assertion fails'
Because i think the output logic should just format it so that it looks
nice (e.g. less < 76 characters per line) and retain the correct
semantics of the original statement. I wouldn't worry about the
original input format, though. If this proves too hard then maybe blame
Armin who suggested the 'comma'-try-parsing-withought-understanding-the
expression-tricks :-)
Regarding your string-parsing question ...

I think you are mixing the string s with its repr-esentation in source code.
When you actually try-to-parse
self.assertNotEquals('''
aaa
bbb
ccc
''', s)
then you will at some point pass "'\naaa\nbbb\nccc'" to parser.expr()
which will succeed.
HTH and happy recovery,
Holger
