even if you use python's "+=" you need to write 'modLine = ""' first.
'modLine += text' would assume that modLine is already defined. This might
be strictly necessary with python's type of typing (combined with the
"refusal to guess in the face of ambiguity") or just a mater of "Explicit
is better than implicit". Do an "import this" to get more of python's
tellings :-)

tutor absolutly meets my opionion of a active list (as you should have
already expirienced ;-). You possibly have seen those rediculess "far in
future posts" (mostly due to a very badly adjustet system clock - but how
knows, maybe those guys have a time machine indeed? ;-). Make shure you
request the archives for recent months.
