What is the difference between <class 'str'> and <type 'str'>

阅读更多关于 What is the difference between and

When I try to manipulate this str in 'for loop': for ID in response: The 'response' is read NOT by line, BUT by character. I intend to put every line of 'response' into individual element of a list. Now I have to write the response in a file and use 'open' to get a string of <type 'str'> that I can use

Codable and XMLParser in Swift4

阅读更多关于 Codable and XMLParser in Swift4

Using Swift4, iOS11.1, Xcode9.1, Using the new Swift4 typealiase "Codable" works well for JSON-decoding (as explained here or here or in many other contributions). However, as it comes to XML-parsing, I couldn't find any information on whether this "Codable" protocol could also be used for XML-decoding. I tried to use the XMLParser (as can be seen in code-excerts below). But I failed to used the "Codable" protocol as to simplify the XML-parsing process. How would I have to use the Codable-protocol exactly to simplify XML-parsing ?? // the Fetching of the XML-data (excert shown here with a

1、使用decode判断字符串是否一样 decode(value,if1,then1,if2,then2,if3,then3,...,else) 含义为 IF 条件=值1 THEN 　　　　RETURN(value 1) ELSIF 条件=值2 THEN 　　　　RETURN(value 2) 　　　　...... ELSIF 条件=值n THEN 　　　　RETURN(value 3) ELSE 　　　　RETURN(default) END IF 示例： 2、使用decode比较大小 select decode(sign(var1-var2),-1,var1,var2) from dual sign()函数根据某个值是0、正数还是负数，分别返回0、1、-1 示例： 3、使用decode函数分段工资大于5000为高薪，工资介于3000到5000为中等，小于3000为低薪示例： 4、利用decode实现表或者视图的行列转换 5、使用decode函数来使用表达式来搜索字符串 decode (expression, search_1, result_1, search_2, result_2, ...., search_n, result_n, default) decode函数比较表达式和搜索字，如果匹配，返回结果；如果不匹配，返回default值；如果未定义default值
