So you are using exec to process an assignment statement.  The setattr
builtin function will do what you want.

http://docs.python.org/lib/built-in-funcs.html#l2h-64

so your code could wind up looking something like:

setattr( self,
    'h_' + each[:-2].lower().replace('-','_'),
    significant_headers[each]
    )

Looking at that code, you can pull the key and value from
significant_headers in the for statement.  That is:

for key,val in significant_headers.items():
    setattr( self,
        'h_' + key[:-2].lower().replace('-','_'),
        val
    )

Now the line that actually determines the attribute name looks pretty
ugly.  I would recommend writing a function to replace that operation
with an understandable function name (perhaps key2name).  That would
result in:
    setattr(self, key2name(key), val)


Hope this helps.  The ease with which Python allows you to attach names
to values is one of the great features of the language.
