Excerpt: The representation of a string inside Python is Unicode encoding, so in encoding conversion, it is usually necessary to use Unicode as the intermediate encoding, that is, to decode the other encoded characters (decode) into Unicode, and

Ordinary strings in the py2.7 are ASCII-encoded, for example, str= "ABC", if it contains Chinese will be GBK or gb2312 code (GB2312 is the Chinese provisions of Chinese character coding, also can be said to be Simplified Chinese character set

#-*-coding:utf-8ImportSYS" "* The first thing to figure out is that the representation of a string inside Python is Unicode encoding, so in the case of encoding conversion, it is usually necessary to use Unicode as the intermediate encoding, that is,

Oracle Decode () functions and case statements are all common use, so what is the difference between them? Here's a detailed description of The difference between the Oracle Decode () function and the case statement for your reference. First, give

The difference between IS and = =:To know the difference between IS and = =, let us first look at the ID () method, the return value of the ID method is the memory address of the object , in short, this will give us a bunch of values can not

The representation of a string inside Python is Unicode encoding, so in encoding conversion, it is usually necessary to use Unicode as the intermediate encoding, that is, decoding the other encoded string (decode) into Unicode first. From Unicode

Following excerpt from: http://www.jb51.net/article/17560.htmWhy Python Use the process will appear a variety of garbled problems, obviously the Chinese characters are displayed as "\xe4\xb8\xad\xe6\x96\x87" form?Why is the error "Unicodeencodeerror:

In oracle decode, if the result of the decode function is an aggregate function, you must add the value or item of the decode judgment to the group by statement, for example, www.2cto.com select. C _ FUNDCODE, A.D _ REGISTERDATE, DECODE (. C _ FLAG,

[Original] basics: Article 4. There are two important methods in ext: decode and encode. Before proceeding to this example, I suppose you already know what JSON data is, so let's review it here: JSON (JavaScript Object Notation) is a data exchange
