Also, if you type ' defs ' then press TAB in a Python file it would setup a generic function.You can also create your own s
first, let's talk . MarkDown Editor, I feel it is very convenient, because used to LaTeX , for MarkDown It 's easier to get started, but I've found that MarkDown There are several problems that have not been able to find a specific solution:
the picture size problem. In LaTeX We can adjust the size of the image to fit the entire text;
font, font size setting. MarkDown inside the title is quite big, but the
options for use
That's why THE PEP 0263 is only given to Python's official advice.
This recommendation is:

In practical application, the XML configuration file needs to be modified in real time.
1. Add and remove certain nodes
2. Add, delete, modify some properties under a node
3. Add, delete, modify the text of some nodes

Python processes text line break instance code, and python line feed

Each line of the source file is followed by a carriage return, so when the following output is u
-value structure in JSON is much simpler and more straightforward than the structure of XML. We can also extend the JSON. such as the following data. inside the key value of the record is an array with 2 dictionary data inside the array. data={' name ':' ZHF ' :30 : ' China ' ' record ' :[{ ' first ' : China ' ' during ' :10},{ ' second ' : ' Chengdu ' , Span lang= "en-us" > ' during ' :20 You can see that JSON can store complex data structures. When we print it
