Sort several data structures in Python, including lists, dictionaries, tuples, sets, and python data structures. List: shoplist = ['apple', 'mango', 'carrot', 'bana']Dictionary: di = {'A': 123, 'B': 'something '}Set: jihe = {'appl

Specifically, the specifics of the implementation of the encapsulation to ensure that the user is not visible, which is information hiding (information hiding), such as:Python is a simple review in the next section, and if you are a beginner in python or unfamiliar with many concepts, it is recommended that you learn about Python's basic syntax and common modules, which provide some resources for learning: Official

What is a data structure?Data structure refers to the existence of one or more relationships between the collection of elements and the data elements in the collection of the relationship between the composition.Here's an example to understand this data structure:Data can be likened to books,

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
