I have some code that I inherited:
' '.join([self.get_abbrev()] +
[str(f['value')
for f in self.filters
if f.has_key('value')]).strip()
This broke today when it encountered some non-ascii data.
I changed the str(f['value']) line to f['value'].encode('utf-8'),
which works fine, except when f['value'] is not a string (it could be
anything).
Without rewriting this without the list comprehension, how can I write
this to deal with both strings and non-strings?
