Have learned a python, like his style. Like library concepts, variable definitions, programming styles are all like. The concept of pointers is not very understanding, C + + stay in the VC6.0 era of freshman. Want to learn another fast-compiling language. Which would compare rust and go and recommend one based on the above. (Better to compare the details of the content.) Reply content:If you take the time

After reading the Python indentation, now look at Python identifiers, quotes, and annotations. IdentifierThe identifier for Python is not unique, but there are certain rules.Identifiers are the names that are used when programming. In Python, identifiers have several eleme

一旦无数据，则报错。 sk.accept()　　接受连接并返回（conn,address）,其中conn是新的套接字对象，可以用来接收和发送数据。address是连接客户端的地址。　　接收TCP 客户的连接（阻塞式）等待连接的到来sk.connect(address)　　连接到address处的套接字。一般，address的格式为元组（hostname,port）,如果连接出错，返回socket.error错误。sk.connect_ex(address)　　同上，只不过会有返回值，连接成功时返回 0 ，连接失败时候返回编码，例如：10061sk.close() 　　关闭套接字sk.recv(bufsize[,flag])　　接受套接字的数据。数据以字符串形式返回，bufsize指定最多可以接收的数量。flag提供有关消息的其他信息，通常可以忽略。sk.recvfrom(bufsize[.flag])　　与recv()类似，但返回值是（data,address）。其中data是包含接收数据的字符串，address是发送数据的套接字地址。sk.send(string[,flag])　　将

First of all, the programming language is divided into compiled, interpreted and mixed type, where Python is an interpreted language, the following table is the common language classificationCompiled vs explanatory typeCompiled typePros: Compilers typically have pre-compiled procedures to optimize code. Because the compilation is done only once, the runtime does not need to compile, so the program execution

Python2 and Python3 in a little bit different, but for programming is not too big difference, in the release notes, Python2 official support until 2020, so when learning to use Python3 version: 1, the difference between print, In Python2, you can use the print "name" directly, such expressions, in the Python3 must be bracketed, such as: Print ("name"), so more canonical. 2. Python character encoding support
