We like to use arrays for data lookup, because the array is a "random access" data structure, we can directly calculate the storage location of each array element based on the starting address and the subscript values of the arrays, so its lookup

New versions of Python introduce new features, but in fact these features already exist in the previous version. To "try out" a new feature, you can do so by importing some of the features of the __future__ module.For example, the integer division
