• Configure Code Snippets
• code-Preferences-User code snippet, select Python
• In the configuration file, enter the content you want to define, and the field has the following meanings:

Prefix: This parameter is a quick entry to use the code segment. For example, if the log is used, the input log will be intellisense.
Body : This is the body of the code segment. The code to be set is placed here, and the line break between strings is separated by \r\n newline. Note that if the value contains special characters, it needs to be escaped.
$1 : This is the location of the cursor.
$2: After using this parameter, the next position of the cursor will start another line, press tab to switch quickly.
Description : description of the code segment, description when using IntelliSense

• The complete configuration file instance is as follows:

2. {
4. /*
6. //place  Your Snippets forpython hereeach snippet is defined Under a snippet Name and has a prefix  body and
8. // description the prefix is what  is used to trigger the Snippet and the body would be Expanded and inserted possible variables are:
10. // $1,< Span class= "PLN" > $2 for tab stops, $0 for the final cursor position ,and ${1 :label}, ${< Span class= "lit" >2:another}for  placeholders. Placeholderswith&NBSP;THE&NBSP;
12. // same ids are connected.
14. //Example:
16. "Print to console":{
18. "prefix":"log",
20. "body":[
22. "console.log(‘$1‘);",
24. "$2"
26. ],
28. "description":"Log output to console"
30. }
32. */
34. "Input Note":{
36. "prefix":"itne",
38. "body":[
40. "‘‘‘",
42. "Function Name : diff_Json_Same",
44. "Function : General comparison xx method",
46. "Input Parameters: jsonastr,jsonbstr",
48. "Return Value : None",
50. "‘‘‘"
52. ],
54. "description":"Input the class or function notes!"
56. }
58. }

• How to call: Enter the Itne carriage return in the Python file, then enter the definition code snippet

• Configure shortcut keys
