At least using Python 2.0 on a FreeBSD webserver, this could possibly raise
an exception.

instead use

try: 
   VAR1 = form['var1'].value
except: 
   VAR1 = ''

if the person submitting the form leaves the "var1" textfield blank,
cgi.FieldStorage() won't know form['var1'].value exists.

As for the rest... """ is your friend.
