PEP8 Coding Specification This blog is a translated version of PEP8https://my.oschina.net/u/1433482/blog/464444 Divided into 7 main parts It is important to keep the consistency of the code because it must read more code than write code during the development process. 1. Code layout Indent: Four spaces Multi-parameter hanging or vertical indentation in the method: Select line break in the IDE at the end of the

The problem of Chinese coding is always a headache in Python programming, this paper summarizes it in detail. Specifically as follows:When the string is: ' \U4E2D\U56FD ' >>>s=[' \u4e2d\u56fd ', ' \u6e05\u534e\u5927\u5b66 '] >>>str=s[0].decode (' Unicode_escape ') # Encode ("Euc_kr") >>>print str China When the string is: ' An East Asian school group ' >>>print UNICHR (19996) East

1. Describe two lines in the following code #The first line of comments is to tell the Linux/os x system that this is a python executable and the Windows system ignores this comment;The second line of comments is to tell the Python interpreter to read the source code according to the UTF-8 encoding, otherwise the Chinese output you write in the source code may be garbled.#!/usr/bin/env

the ASCII code storage space, So there's a UTF-8 encoding that converts Unicode encoding into variable-length encoding; in computer memory, Unicode encoding is used uniformly, and is converted to UTF-8 encoding when it needs to be saved to the hard disk or when it needs to be transferred.Python's string type is str, in memory in Unicode, a character corresponding to a number of bytes, if you want to transfer on the network or save to disk, you need to turn str into bytes.In

First, understand the difference between encode () and Decode () The role of Encode () is to convert a Unicode-encoded string to another encoding format. For example: St1.encode ("Utf-8") is the function of encoding a UNICODE encoded ST1 as a UTF-8 encoded string The role of Decode () is to convert strings of other encoded formats into Unicode-encoded strings. For example: St2.decode ("Utf-8") is a sentence that decodes a utf-8 encoded string st2 into a Unicode-encoded string Second, in add
