Raw Newbie: What's the "<?" tag and how can I learn more about it?

[KEVIN ZEMBOWER]

Thank you, Alan, holger and Simon, for all your help.

The '%%' worked like a champ.

It never occurred to me that the author of ezmlm-browse would have written his own template system. Thank you for removing this source of frustration. Some of the files in the system are copyright Bruce Guenter, so I'll write to him with any further questions.

Thanks, again, for all your help.

As Simon mentioned already, that's because it's not part of core python,
it belongs to whatever template system ezmlm uses.

I don't know for certain, but the "100%" may be being interpreted as a
python "format string". See these urls for information on format
strings.

http://www.python.org/doc/current/tut/node9.html 
http://sandbox.mc.edu/~bennet/python/code/io.html 

IFF it is a format string, then the solution is to double up the % sign:
i.e. express it like so "<table width='100%%'>".

However, if that isn't the problem, I don't have any further suggestions
to make.
