Python version--Verification code check dozen Code Rabbit platform Application Introduction 1. Background The full name of the verification Code (CAPTCHA) is a fully automated Turing test that distinguishes between computers and humans (completely automated public Turing test to tell Computers and humans). It is a challenge answering system test for distinguishing human from computer automatic program. Captcha can differentiate between humans and au

side-by-side. Use empty lines to separate functions and classes, and large chunks of code in functions. If possible, comment exclusive line Working with document Strings Place the space on either side of the operator and behind the comma, but no space is added to the brackets: a = f (1, 2) + g (3, 4) . Uniform functions and class naming.The recommended class names are named with the hump , and the function and method names are underlined in lowercase _ and _ . Always use self a

, after restarting the interpreter, it will be found that the encoding is reset to the default ASCII, Then there is no way to modify the program or the system's default code at once.There are 2 ways to set the default encoding for Python:A solution is to add the following code to the program:python code NBSP;NBSP; Import Sys Reload (SYS) Sys.setdefaultencoding (' UTF8 ') Another option is to create a new sitecustomize.py under the

Python has always been a bad supporter of Chinese, recently encountered coding problems, and there are few common solutions to solve this problem, but after the common methods have been tried, the discovery can still be resolved, the following summarized the commonly used to support Chinese coding problems (these methods may be one of these can solve the problem,

the file is encoded internally.1) ANSI: The encoding of the file is two bytes "D1 CF", which is the "strict" GB2312 coding, which also implies that GB2312 is stored in the big head way.2) Unicode: Encoding is four bytes "ff fe 4E", where "FF fe" indicates a small head mode of storage, the true encoding is 4E25.3) Unicode Big endian: The encoding is four bytes "Fe FF 4E 25", wherein "FE FF" indicates that the head is stored in the way.4) UTF-8: The en

First, these problems only occur in python2.X, because in python 3. X, only unicode strings are available, that is, all processed in the program are automatically converted to unicode strings. So how can we avoid and clarify the encoding problem during python Program Development in 2.x? First of all, we must maintain a good unified rule. Otherwise, everything will be white. It is best to use UTF-8 in a unif

Encoding of Python code filesThe py file is ASCII encoded by default, and Chinese will make an ASCII-to-system-default-encoding conversion when displayed, and an error will occur: Syntaxerror:non-ascii character. You need to add an encoding indication on the first or second line of the code file: # coding=utf-8 ##以utf-8编码储存中文字符 print ' Chinese ' as above directly input string is processed accor

When using Python to write crawlers, you often encounter a variety of maddening coding errors. Here are some simple ways to solve the problem of coding errors, I hope to help you . First, open the site you want to crawl, right-click to view the source code, and see what it specifies, such as:　　http-equivcontent= "text/html; charset=gb2312"> The charset I specify
