我们从Python开源项目中，提取了以下22个代码示例，用于说明如何使用google.protobuf.message.repeated_nested_enum()。
def testAssignUnknownEnum(self): """Assigning an unknown enum value is allowed and preserves the value.""" m = unittest_proto3_arena_pb2.TestAllTypes() m.optional_nested_enum = 1234567 self.assertEqual(1234567, m.optional_nested_enum) m.repeated_nested_enum.append(22334455) self.assertEqual(22334455, m.repeated_nested_enum[0]) # Assignment is a different code path than append for the C++ impl. m.repeated_nested_enum[0] = 7654321 self.assertEqual(7654321, m.repeated_nested_enum[0]) serialized = m.SerializeToString() m2 = unittest_proto3_arena_pb2.TestAllTypes() m2.ParseFromString(serialized) self.assertEqual(1234567, m2.optional_nested_enum) self.assertEqual(7654321, m2.repeated_nested_enum[0]) # Map isn't really a proto3-only feature.
