on the front end:1if JSON is converted by a list object, you can directly traverse the JSON to read the data. 2If you need to convert the front-end list object to JSON to the background, param is the AJAX parameter, then the conversion is as follows: Var jsonstr=json.stringify (list); var param={}; Param.jsonstr=Jsonst

The lower method of the string object can be used to convert Python strings in lower case. The following example shows the lower method: For example, String object mM = 'affefea' Call the lower method of the string.Print M. Lower () Output result: afefefeaa Next we can use islower () of the

memory space, and then release the memory space. The efficiency is very low. You may not be able to see it when you operate a small amount of data, however, when you encounter a large amount of data operations, this method is about to retire. Let's take a look at the following two advanced methods. Advanced Method 1: Use the string join method: a = ['a','b','c','d']content = ''content = ''.join(a)print content Result of content: 'abc' Advanced Method
