@property can access a Python-defined function as a property, providing a more friendly way to access it, but sometimes setter/getter is needed.classpeople:def __init__(self,name,weight,height): Self.__name=name Self.weight=Weight Self.height=Height @propertydefBMI (self):returnSelf.weight/(self.height**2) @bmi.

The code is as follows
Copy Code
BufferedImage image= bim;//Two-dimensional codeBuffere
([' foo ', ' Bar ', ' baz '], function (idx, val) {
console.log (' element ' + idx + ' is ' + val);
});
$.each ({foo: ' Bar ', Baz: ' BIM '}, function (k, v) {
Console.log (k + ': ' + V);
});
Returns the index of an element in an array and returns 1 if the element does not exist
var myarray = [1, 2, 3, 5];
if ($.inarray (4, myarray)!==-1) {
console.log (' found ');
}
To extend another object with one object:

following parameters:
URL: The requested URL must be provided.Data: Available to the server, optional. Can be an object, or a query string, such as Foo=barbaz=bim.
Note: This option does not apply to $.getscript.
A callback function: This callback function is triggered after a request has been successfully executed. Optional. The callback function accepts data returned by the server, and also includes the requested status code and origin
client order is defined as the network byte order.
Berkeley Socket API defines a set of conversion functions for 16 and 32-bit integers in the network order andLocal byte order. Htonl and htons are used for local sequence conversion to network sequence; ntohl and ntohs are used for network sequence conversion to local sequence.# Define ntohs (n) // network byte order to host byte order n Represents net, H represents host, s represents short # define htons (N) // host byte order to network byte
Description
Little Tom loves playing games. one day he downloads a little computer game called 'bloxorz' which makes him excited. it's a game about rolling a box to a specific position on a special plane. precisely, the plane, which is composed of several unit cells,Is a rectangle shaped area. and the box, consisting of two perfectly aligned Unit Cube, may either lies down and occupies two neighbouring cells or stands up and occupies one single cell.

the rescue is expressed as "the knight has reached the place where the princess is". As the guard may be encountered on the road leading to the princess's location, once the knight encounters the Guard, the guard must be killed to move on.It is assumed that the knight can move up, down, left, and right in four directions, requiring 1 units of time per move, and killing a guard takes an additional 1 units of time. Also assume that the knight is strong enough to kill all the guards.

class naming rules. In addition, if an exception actually refers to an Error, Use "Error" as the suffix.
Try to use full spelling words for naming. There are two abbreviations: Common abbreviations, such as XML and ID. Only the first letter, such as XmlParser, should be capitalized. The name contains long words, which are abbreviated to a word. In this case, we should use the abbreviated form of conventions. For example, function stands for fn, text

fread, what we get is no longer 0x3132 but 0x3231, and the data we read is incorrect. Therefore, we need to be careful when transmitting data on two machines with different bytes, understanding the byte sequence can help us write more code. because of the differences in the byte sequence, big-Endian is used to define all data related to the byte sequence during network transmission. The BSD Code defines four macros for processing: # define ntohs (n) // network byte order to host byte order n Re
