Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza.9-13 Use OrderedDict: In Exercise 6-4, you used a standard dictionary to represent the vocabulary.

Moreover, the kind of big rats have very strong teeth. It's a piece of cake to bite off their arms and legs in three or two, and they move very quickly." Zhang Xiaobo said.
