shaped exclusion): text wraps around a rectangular area. area style (Region styling): displays content based on the flow area. The following are examples of various classifications: Content Flow In a typical HTML document, text can be displayed in more than one area, but the text in each area is irrelevant (see Figure 1). If you want to display text across multiple columns, or use other more complex areas you need to manually. This may not

Python functools module learning Summary This article mainly introduces the Python functools module and explains functools. partial, functool. update_wrapper, functool. wraps, functools. reduce, functools. cmp_to_key, functools. examples of total_ordering and other methods. For more information, see Document address Functools. partial Purpose: Functools. partial allows us to "redefine" the function signature by means of packaging. Wrap a callable obje

1. PrefaceThe first step in using jquery is to get the jquery object, and there are two main ways to get the jquery object in the Jquey library:1) Use the $ () function or a jquery object to return a jquery object using a parent-child relationship.2) The JQuery object's call method changes itself and returns the JQuery object again.So the jquery () function gets the important path to the jquery object, which is mainly used as follows:1) jquery (Expression,[context]): This function gets the jquer

BONUS #2: Use functools. wraps to save docstrings and function names Unfortunately, one side effect of using the decorator is that the method name (name) and docstring (doc) values are not saved: def increment(f): """ Increment a function result """ wrapped_f(a, b): return f(a, b) + 1 return wrapped_f@in

The decorator in python can be used at the same time, as shown below: Copy codeThe Code is as follows:@@ B@ CDef f (): pass# It is same as belowDef f (): passF = A (B (C (f ))) Iii. decorator instances commonly used in Python Decorator is usually used to perform permission authentication, logging, or even modifying input parameters before execution, or preprocessing the returned results after execution, or even truncating the execution of functions.

They are texture objects.The property wireframe specifies whether the surface boundary is rendered. If rendered, several attributes starting with wireframe indicate how the boundary will be rendered.Texture: Texture This constructor is used

properties like that, but you see the functions after the decorator decoration, and they __name__ have changed from the original ‘now‘ ‘wrapper‘ :>>> now. __name__ ' wrapper 'Because the name of wrapper() The function returned is the same, ‘wrapper‘ so you need to copy the properties of the original function __name__ into the wrapper() function , otherwise, some code that relies on the function signature will be executed with an error.There is no need to write wrapper.__name__ = func.__name__
