To get a single % use %%. For example, running python from the command 
line this fails:

 >>> t = '%(fred)s:%(bert)s x="100%"'
 >>> v = {'fred': 'abc', 'bert': 'xyz'}
 >>> t % v
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
TypeError: not enough arguments for format string

but this succeeds:

 >>> t = '%(fred)s:%(bert)s x="100%%"'
 >>> v = {'fred': 'abc', 'bert': 'xyz'}
 >>> t % v
'abc:xyz x="100%"'
