.x version, the encoding of the string is Unicode and the others are utf-8. However, there is a problem, then the string as a network transmission, local storage data type, encoding type Unicode, is not allowed. What's going to happen?At this point, there is a basic data type of bytes in Python. The bytes type is comparable to the STR type of the twin brothers, Str type all methods, bytes types can be used.# # # bytes types differ from str types? ###

Apply has a twin brother Call,call and apply are meant to change the context in which a function runs, in other words, to change the direction of this within the function body.

The members of the mutable keyword adornment can be changed.The const member function is used to implement the Non-const twin to avoid duplication of code.Remember:Declaring something as const can help the compiler detect the error usage. A const can be applied to objects, function arguments, function return types, and member f

In the table table element, there is a COL element (it also has a twin elder brother Colgroup Element), which is called the column element in the universal standard, and is used to define representations in certain columns in the table, and in the current and common tutorials, it is considered that the COL element can use common global properties. And align, valign, width and so on attributes (even HTML 4.1 and 5.0 specification documents, also agree

A, one of the rewrite rules:The overriding method cannot have a stricter access level than the overridden method limit. (but more broadly, such as the parent class method is the package access permission, the subclass's overriding method is public access.) )For example: The object class has a ToString () method, it is always easy to forget the public modifier when we begin to rewrite this method, and the compiler will of course not miss any chance to teach us. The reason for the error is that th

In addition to using page breaks, another twin brother section break is a common tool when editing documents. It enables the header and footer settings for the previous pages to be different from the following pages. Today's small series for you to introduce the use of the WPS Word section break.
A section break is a section that can be a different section on the same page, or it can be divided into sections at the same time as the next page.

. The sub-problems produced by the Division method are often the smaller models of the original problems, which makes it convenient to use "recursive technology" . In this case, the repeated application of the method of separation, can make sub-problems and the original problem type consistent and its scale is shrinking, and finally make the sub-problem to easily find its solution, which naturally leads to the generation of recursive process. " Divide and conquer" and "recursion " like a pair

Func ()
This is the most common way of calling, and is ubiquitous in any language. Func (x, y) can pass in different parameters. In some languages, such as Php,java, this call is sufficient to solve all problems. But JavaScript is a functional language, the concept of closures and a strange keyword this determines the inadequacy of this invocation approach. This should be interpr
State mode
As we talked about the strategy model, here's a look at the twin brothers of the Strategy model: State mode.
State patterns, which allow changes in the intrinsic state of an object to change its behavior, the object looks like it changes its class.
The first time I read this definition, it was almost a shock, and I didn't know what he was saying, one sentence, and when the internal state of an object changed, it was allowed to change its be
