What does %%(%s)s mean in Python?
Weird question, as this has nothing to do with the code you just posted.
In general, what comes up to my mind, is that it is a format string to
build another format string.
Example:
metafmt = '%%(%s)s'
fieldname = 'myfield'
fmt = metafmt % fieldname
# Now we have a fmt as if it was assigned with '%(myfield)s':
# %% -> %, %s -> myfield.
d = {fieldname: 'my content'}
print fmt % d
# this now prints the given field - which is noted in fieldname -
# from the given dict d.
