Solve the following python programming problem given the following code:
def _write_spec_file(self, instance, rpm_name, template_name, params) : 
    requires_what = params.get ('requires', []) 
    conflicts_what = params.get ('conflicts', []) 
    test_requires_what = params.get ('test_requires', []) 
    test_conflicts_what = params.get ('test_conflicts', []) 
    egg_info = getattr (instance, 'egg_info', None) 
    if egg_info : 
        def ei_names(key) : 
            try : 
                requires_python = [str (req) for req in egg_info [key]] 
except KeyError : 
                return ([], []) 
else : 
                return self.py2rpm_helper.names_to_rpm_deps (requires_python) 
(rpm_requires, rpm_conflicts) = ei_names ('dependencies') 
        requires_what.extend (rpm_requires) 
        conflicts_what.extend (rpm_conflicts) 
        (rpm_test_requires, rpm_test_conflicts) = ei_names ('test_dependencies') 
        test_requires_what.extend (rpm_test_requires) 
        test_conflicts_what.extend (rpm_test_conflicts) 
params ['requires'] = requires_what 
    params ['conflicts'] = conflicts_what 
    params ['test_requires'] = test_requires_what 
    params ['test_conflicts'] = egg_info 
    params ['epoch'] = self.OPENSTACK_EPOCH 
    params ['part_fn'] = (lambda filename : sh.joinpths (settings.TEMPLATE_DIR, self.SPEC_TEMPLATE_DIR, filename)) 
    parsed_version = pkg_resources.parse_version (params ['version']) 
    params.update (self._make_spec_functors (parsed_version)) 
    content = utils.load_template (self.SPEC_TEMPLATE_DIR, template_name) [1] 
    spec_filename = sh.joinpths (self.rpmbuild_dir, 'SPECS', ('%s.spec' % rpm_name)) 
    sh.write_file (spec_filename, utils.expand_template (content, params), tracewriter = self.tracewriter)
