memory is limited and integer values are not infinite. For example, print (type 2**100), the output is int.float:Decimals, for example 3.23. Science counts, 5.2E-4, equivalent to 5.2*10**-4.Boolean value:True or False (Ture/false), 1 or 0 (only 1 and 0 represent true and false).five or three-dollar operationresult = value 1 if condition else value 2. That is, when the IF condition is true, result is a value of 1, otherwise the value is 2.eg.A,b,c = 1,3,5result = A If a>b else CPrint (Result)vi.

DictionaryAnother useful Python built-in data type is dictionary.The sequence is index
In python , the characteristics of an object are also known as attributes (attribute). The behavior it has is also called the method. Conclusion: Object = attribute + method In python , classify objects with the same properties and methods as one class such as humans, animals, plants, etc., these are the concepts of the class.A class is a template or blueprint for an object, a class is an abstraction of an object, and an object is an instantiation of a class. A class does not represent a
methods.var box = new Object ();//Create an object box.name = ' Lee ';//Create a Name property and assign a value Box.age = 100;//Create an Age property and assign a value Box.run = function () {//Create a run () method and return a value of return this.name + this.age + ' running ... ';}; Alert (Box.run ());//Output properties and method values The above creates an object and creates properties and methods, and this in the Run () method represents the box object itself. This is the most basic

dictionary. the keywords in the list are unordered. If you want to sort the keywords, you can use sorted (d. keys ()). you can use the in keyword to check whether a single keyword is in the dictionary.
The following is a simple example of using a dictionary:
>>> Tel = {'jack': 4098, 'sape ': 4139}
>>> Tel ['guid'] = 4127
>>> Tel
{'Sape ': 4139, 'guide': 4127, 'jack': 4098}

So how does cron work? This depends on your system environment. I will only discuss the old-fashioned simple cron UNIX Command Line version. You can ask the system administrator how to implement it in your Web application.
The following is a simple cron configuration. It run

Because attributes do not belong to the class, they belong to instances of each class. That is, it belongs to the object.
So we can set different properties for each instance.
