Best way to deal with different data types in a list comprehension

[Rock Neurotiko]

Maybe there are a different way, but you can do this:

' '.join([self.get_abbrev()] +
           [str(f['value').encode('utf-8') if type(f['value']) is str else
str(f['value']
            for f in self.filters
            if f.has_key('value')]).strip()
