; so let's do a manual simulation, Disguise it to write __doc__ and __name__ReformManual copy: Coarse modification, __doc__ __name__ forcibly copied into the instanceSelf is nothing more than an instance of the class we are currently bound to, and FN is passed in by the adorner, and we assign FN's doc and name as the source forcibly to the self, as follows:Class Timeit:def __init__ (SELF,FN): Print (' init ') Self._fn = doc copy of fn# function to fn self.__doc__ = SE lf._fn.__doc__ self.__name_

%s called [%s]."% (func.__name__, arg)) return __deco return _decodef myfunc (): Print ("MyFunc () called.") def myfunc1 (): Print ("MyFunc () called.") MyFunc = Deco () (myfunc) myfunc1 = Deco ("Haha1") (MYFUNC1)Then look at the use of wraps in standard library functools, such as the official website example:From Functools import Wrapsdef my_decorator (f): @wraps (f) def wrapper (*args, **kwds): print ' ca

Data Source:Effect:Each data and TextBox bindingRealize:Using ItemsControl, set the Itemspanel label, the data type is itemspaneltemplate.The entry container for the control ItemsControl is wrappanel,orientation= "Vertical" and can be arranged vertically.The height of the ItemsControl and textbox are defined separately, and the line wrapping is implemented in a vertical arrangement.Attention:ItemsSource is int[] or listYou need to convert int[] or listWPF implements vertical alignment and

How the alert () Popup content wraps:About alert () warning box Everyone should be not unfamiliar, sometimes we need to wrap the popup content, so that the content is more structured, the following is a brief introduction to how to achieve this effect, first look at the wrong operation, the code is as follows:Alert ("1. User name cannot be empty The above code can not be wrapped, because The correct way is as follows:Alert ("1. The user name cannot be empty.) \n2. The password cannot be empty. "

example, a garbled character such as the following is added to the page header: "" Nobelium? "1. For example, when we combine several JS files into a single file, if the middle of the file contains BOM characters, it will cause the browser JS syntax error.2.PHP does not recognize the BOM header, PHP does not ignore the BOM, so when reading, including or referencing these files, the BOM is used as part of the text at the beginning of the file. Depending on the characteristics of the embedded lan

First, after entering word, click the "Insert"--> picture in the menu bar--> from the file, and then find the picture you want to insert, click "Insert"! Ways to set text wrapping around a picture in Word Right-click the picture, in the Pop-up drop-down menu, select "Format Picture" inside the "layout", at this point, we can see a variety of different text around the way the picture! The following figure: 　　Here is a description of the 5 types of text around the meaning of the way

In Python, an adorner is used to extend some external functionality to a function at run time. However, in the process of use, because of the addition of adorners that cause the interpreter to think that the function itself has changed, in some cases-such as testing-will cause some problems. Python functool.wraps solves this problem for us: When you write an adorner, adding it before implementation @functools.wraps(func) ensures that the adorner does not affect the decorated function. For exampl

logic is encapsulated in the elevator state class, so the logic of the judgment is relatively simple, do not consider the situation under a variety of conditions, only consider how to deal with the current state, for example, we look at the elevator upstream state how to handle the door action: public Span style= "COLOR: #000000" > void opendoor () { System. out . println ("Can ' Topen the door during move." );}It is not necessary to make any logical judgment at this time,

Among them, Table-layout:fixed says:The column widths are set by the table width and column width. In a fixed table layout, the horizontal layout depends only on the table width, column width, table border width, cell spacing, and the contents of the cell. Among them, Word-break:break-all says:The Word-break property specifies how the wrap is handled.

problem.When we deploy to the server, the server is the Linux environment, the newline read system line break is \ r, exported to a file, the file line break is \ r, when we download this file through the browser to Windows, then open the file will be there is no line-wrapping problem. Because the explanation for \ r under Windows is not a line break.Therefore, when developing, we cannot use the newline method if we need to specify that the file should be wrapped in some places.
