Python's C language see the appropriate PEP guide 1. This document, along with Pep 257 (specification of document Strings), is adapted from Guido's original Python style Guide, while adding some of Barry's style guide 2. This normative guide evolves over time, and as the language itself changes, the conventions of the past are eliminated. Many projects have their own coding specifications, in the event of

Talking about the coding process of Python crawling web pages, talking about python crawling code Background During the mid-autumn festival, A friend sent me an email saying that when he was crawling his house, he found that the Code returned from the webpage was garbled and asked me to help his adviser (working overtime during the Mid-Autumn Festival, really ded

Summary of coding knowledge in python, python Encoding Problem During normal work, I encountered the following error: UnicodeDecodeError: 'ascii' codec can't decode byte It is common that everyone has encountered it. So I decided to organize and learn python encoding. Basic knowledge In python2.x, there are two data ty

Unicode formatS1.encode ("UTF8") successS2.encode ("UTF8") success3. When Chinese is present:S1 = "Hello"--utf-8 encoded. Why is it not ASCII under Linux? Does the ASCII mean Chinese?It must have been converted for utf-8.S2 = u "Hello"S1.encode ("UTF8") errorS2.encode ("UTF8") successWorkaround:First, convert this utf-8 code to Unicode-encoded objectsAnd then into the utf-8.S1.decode ("UTF8").

This book I read the electronic version, feel good, a total of 20 chapters, the book is as follows:This book is designed to enable you to learn Python as quickly as possible so that you can write programs that work correctly-games, data visualizations, and WEB applications-while mastering basic programming knowledge th

Strings are the most commonly used data types in Python, and many times you use characters that do not belong to the standard ASCII character set, and the code is likely to throw Unicodedecodeerror: ' ASCII ' codec can ' t decode byte 0xc4 In position 10:ordinal not in range (128) exception. This anomaly is easy to come across in Python, especially in python2.x, a problem that puzzles beginners. However, if

Before the formal explanation, let's give you a reference: poke hereThe contents of this article refer to this information, and to summarize, in order to avoid my summary is not perfect, or say what wrong place, there are questions about where you can see the above article.Let's start with the coding problem in Python, first of all, we'll see what the coding is.1
