using Python functools.partial SyntaxError: can't assign to function call -

i'm getting error. how fix this? missing using partials?

get_make_models(rows) = partial(groupby_attrs, attributes=['year', 'make'])

syntaxerror: can't assign function call

import itertools functools import partial  def get_keyfunc(attributes):      def keyfunc(row):         """             returns row values attribues joined '-'         """         values_arr = [row[attribute] attribute in attributes]         return '-'.join(values_arr)      return keyfunc  def groupby_attrs(attributes, rows):     keyfunc = get_keyfunc(attributes)     data = sorted(rows, key=keyfunc)     return itertools.groupby(data, key=keyfunc)  get_year_make_models = partial(groupby_attrs, attributes=['year', 'make', 'model']) get_make_models(rows) = partial(groupby_attrs, attributes=['year', 'make']) 

found it, looking @ right end of line. on left, can see variable function call. sorry mistake.

get_make_models(rows) = partial(groupby_attrs, attributes=['year', 'make'])

               ^^^^^^
