ASCII is a character set, including uppercase and lowercase letters, numbers, control characters, and so on, which is represented in a single byte, and the range is 0-127 Unicode is divided into UTF-8 and UTF-16.UTF-8 variable length, up to 6 bytes, characters less than 127 are expressed in one byte, and as with the ASCII character set, the English text under ASCII encoding does not need to be modified to be processed as UTF-8 encoding.Python supports
single byte into a double-byte, only need to fill the high byte all 0 can be.Because Python was born earlier than the Unicode standard, the earliest Python only supported ASCII encoding, and the normal string ' ABC ' was ASCII-encoded inside python. Python later added suppo
In Python, there is a Chinese transcoding problem in Urllib2.urlopen, the workaround is as follows:1.Import BeautifulSoupImport ChardetResponse =urllib2.urlopen ('%s '%line)#response. Decode (' Utf-8 ')#response = Urllib2.urlopen (' http://www.baidu.com/')html = Response.read ()Pdb.set_trace ()#print html.decode (' Big5 ').

ASCII is a character set, including uppercase and lowercase English letters, numbers, control characters, etc, it is represented in a byte, range is 0-9 Unicode divided into UTF-8 and UTF-16. UTF-8 variable length, up to 6 bytes, less than 127 characters are represented in one byte, the same as the results of the ASCII character set, english text under ASCII encoding can be treated as UTF-8 encoding without modification.

Sometimes the return value from the interface is encoded in a format similar to "%u4e0a%u6d77%u60a0%u60a0", not the Unicode encoding in Python.The Unicode encoding inside Python should be this format: \u4e0a\u6d77\u60a0\u60a0Unicode encoding-python21. First look at the Unicode encoding for
Character encodingThe characters in the computer are stored in a specific encoded form, from the earliest ASCII to later Unicode and UTF-8, in Python, the string str is also differentiated encoding, between the various encoded strings, there is a bridge between the Unicode type .STR, UnicodeSTR goes to Unicode and need
Coding problems have always been a headache:
When the string is '\ u4e2d \ u56fd'
>>> S = ['\ u4e2d \ u56fd', '\ u6e05 \ u534e \ u5927 \ u5b66']>>> STR = s [0]. Decode ('unicode _ escape ') #. encode ("euc_kr ")>>> Print Str

Tips for useIn fact, as long as the following rules are followed, you can circumvent the 90% bug caused by Unicode string processing, the remaining 10% can be solved by Python libraries and modules.
You must prefix a string when it appears in the program.
Do not use the STR () function in place of Unicode ().
Don't use outdated string modules--if
The problem this time is still related to Python Unicode. Take a look at the following code:
The code is as follows

In fact, strings are also a type of data. However, there is another encoding problem for strings. The following article describes how to operate strings and encode Unicode in Python. For more information, see the following. This article mainly introduces some knowledge about character string operations and Unicode encoding in
The following tool determines whether unicode is a Chinese character, number, English, or other character. Full-width to half-width. Unicode string normalization. There is also a program that can process the conversion of Chinese characters into pinyin, which is still being compiled.#! /Usr/bin/env python#-*-Coding: GBK -*-"Chinese character processing tool:Deter
Title, in fact, my question is very simple, is to write the crawler when the information contained in the page contains a string similar to "\u65b0\u6d6a\u5fae\u535a\u6ce8\u518c", in fact, this is the Unicode Chinese code, the corresponding Chinese is "Sina Weibo registration." In fact, I just want to find a function to let this string of things display Chinese, did not expect Baidu to find the right day. In this case, do not use what "
In fact, the string is also a data type, but the string is special is also a coding problem. The following article mainly for you to introduce the Python string operation and encoding Unicode details of the relevant information, the need for friends can refer to the following to see together.
This article mainly introduces some knowledge about the string manipulation and encoding
Detailed description of string operations and encoding Unicode in Python, pythonunicode
This article mainly introduces some knowledge about character string operations and Unicode encoding in Python. I will not talk about it here. Let's take a look at it.
String type
str: Unicode
Conversion of Python characters and character values (ASCII or Unicode code value)
This article describes how to convert character strings between ASCII or Unicode values, for more information, see
Purpose
Converts a character to an ASCII or Unicode code, or vice versa.
Method
For ASCII codes (0 ~ Range: 255)
The Code
This article mainly introduces Python character and character value (ASCII or Unicode code value) conversion methods, that is, the string in the ASCII value or between Unicode values and conversion methods, the need for friends can refer to the
Objective
Converts a character to the appropriate ASCII or Unicode code,
