default argument

Decided to start the Python road, using spare time, for more in-depth study of Python. Programming languages are not art, but work or tools, so it is necessary to organize and follow a set of coding specifications. So this afternoon I made a copy

1. Introduction to Functions Why should there be a function? Because in the normal writing code, if there is no function, then there will be many duplicate code, so the code reuse rate is relatively low ... And this kind of code maintenance is also

A function is a block of code that performs some action. A function optionally defines an input parameter that enables callers to pass arguments to a function. The function can optionally return the value as output. Functions can be used to

Look at the next function itself doc Copy Code code as follows: GetAttr (object, name[, default])-> value Get a named attributes from object; GetAttr (x, ' Y ') is equivalent to x.y.When a default argument are given, it is

Look at the code first Copy Code code as follows: printf ("hello,world!"); The number of parameters is 1. printf ("a=%d,b=%s,c=%c", a,b,c) with a number of 4 parameters. How do I write variable parameter functions? Let's

C + + function templatesWe know that data or values can be passed by function parameters, which are unknown when the function is defined, and can only be determined when a function call occurs. This is the parameterization of the data. In fact,

This feature is important and the future will be the core approach to jquery, which radically changes how Ajax is used in jquery. To implement it, all of the Ajax code for jquery is rewritten. However, it is more abstract, difficult for beginners

In C + +, there are three major function copy controls (copy constructors, assignment operators, destructors), while in c++11, move constructors are added to move assignment operators. I would have ventured to name them six functions well. first,

One, what is the deferred object? In the process of developing a Web site, we often experience some very lengthy javascript operations. There are both asynchronous operations (such as AJAX reading Server data), and synchronous operations (such as
