(tuple), the return value must be the same type, otherwise it is always list. For example, the following programs can calculate partial primes:1 def F (x):return and x%3!=02 filter (F,range (2,25))Map (function, seq1,[seq2 ...]) invokes function (item) in turn for each element and returns the return value as a list. For example, the following program computes the cube:1 def Cube (x):return x*x*x2 map (Cube,range (1,10))1 seq = range (8)2def Add (x, y):return x+y3 Map (ADD,SEQ,SEQ)4#ans [0,2,4,

, it is generally necessary to maintain the balance of the generalization relationship: the hierarchy of inheritance should not be too deep (about more than 5 layers to think about), nor too wide (instead of looking for possible intermediate abstract classes)E, association is mainly used for the structure of the object between the place. Do not use associations to represent temporary relationships, such as parameters or local variables of a procedurewhen you use UML to draw relationships, follow

repeatedly by calling write (), but be sure to call F.close () to close the file. When we write a file, the operating system often does not immediately write the data to disk, but instead put it in memory cache, and then write slowly when idle. Only when the close () method is called does the operating system guarantee that all data that is not written is written to disk. The consequence of forgetting to call Close () is that the data may have been written only partially to the disk, and the re

Protobuf (quickStart), protobufquickstart1. Introduction
Protocol Buffers is a data description language developed by Google. It serializes data and can be used in data storage and communication protocols.
It can be understood as faster, simpler, and smaller JSON or XML. The difference is that Protocol Buffers is in binary format, while JSON and XML are in text format.
Compared with XML, Protocol Buffers has the following advantages:
