This example describes the method of defining constants in the Go language. Share to everyone for your reference. The specific analysis is as follows:
The definition of a constant is similar to a variable, except that it uses the Const keyword.
Constants can be values of a character, String, Boolean, or numeric type.
Copy Code code as follows:
Pac
// 1. Standard Method: var myarr: array [0 .. 10] of integer; // defines a static Array
// 2. Non-0 Subscript: var myarr: array [9 .. 10] of integer can be used; // It cannot be promoted, so it is not easy to communicate with system functions.
// 3. declare An Array Based on the predefined type: Type tmyarr = array [0 .. 10] of integer; // first define an array type var myarr: tmyarr; // then define a static Array
// 4. In the
as defining a new command, which is a command, so that each input parameter is separated directly by a space. Once, the command to get the parameters of the method can be passed: $ ... $n get. The $ $ represents the function itself.
3, function return value, only through $? The system variable is obtained, the direct pass =, the obtained is the null value. In fact, we follow the above understanding, know that the function is a command, in the shell

Python's two-dimension dictionary definition and implementation method, twodimensioncode
This article describes how to define and implement the "two-dimension dictionary" dictionary in Python. We will share this with you for your reference. The details are as follows:
Dict in Python allows quick search. Is there a two-dimensional dictionary like an array with two-dimensional arrays? For example, when I need
objects
(1) defined by literal quantity. For example:
var obj = {"Name": "Jim", "Age": 16};(2) New keyword definition. For example:
The code is as follows
Copy Code
var obj = new Object ();Obj.name = "Jim";Obj.age = 16;
4. Properties of objects
To get the property value of an object:
var obj = {"Name field": "Jim", "Age": 16};var name =obj["Name field"]; Property string is a variable or is not a valid identi
recursion:Nested self-tuning behaviorNested invocation of a method does not end until the last method endsIn general, this kind of code needs to be repeated, such as the table of contents, the result is suitable for the use of such nesting.Process:Call the value of I, it will ask I and so not equal to 1, not equal to
The method for assigning values to SQL fields unrelated to the business in the CRUD operation, crudsql
Improving efficiency has always been an eternal topic. One of the topics in programming can also mention efficiency, that is, focusing on one thing and separating other closely related tasks. Here we will share with you the Common Data Processing scenarios we encountered during CRUD:
