python data structures book

There are two main functions in Python: sorted and list member functions sort, except for some differences in invocation methods, the most notable difference is that sorted creates a sorted list and returns, while sort is a good order to modify the original list. The prototype of sorted is:Sorted (iterable, Cmp=none, Key=none, Reverse=false)The prototype of sort is:List.sort (Cmp=none, Key=none, Reverse=false)Where both CMP and key are function refere

element.Filter (): Takes a function as a parameter, returning all elements that enable the function to return true.4. Two-dimensional and multidimensional arraysThere is no two-dimensional array in JavaScript, but you can implement a two-dimensional array by inserting array elements into the array.var twod = []; var rows = 5; for (var i = 0; i i) {= [];}With regard to how to create a two-dimensional array, a best practice is mentioned in the book

The data structure is basically-they are the structures that can handle some data. Alternatively, they are used to store a set of related data. There are three built-in data structures in Pyth
