For beginners, objective-C has a lot of confusing statements, but they are actually very elegant. What programmers write most are functions and functions written by themselves or written by others. This article describes the elegance of objective-C from the perspective of functions.C # and objective-C belong to the C series language. Let's take a look at the definition and call of C # functions for comparison.C # Function Definition:Public void doit (

button on main interface B to exit the entire app, you will need to turn off the B-h-g-b-f-e-d-c-b-a interface in turn. And then the egg ... No one wants to shut it off like this. But let's assume that the B interface (main interface): Android:launchmode= "Singletask", then the boot process from a->b->c->d->e->f->b to the B interface, This is not another time to create a B interface, but the initiative to finish off the C, D, E, F interface and then use the original B interface. And then from t

tamper with the Func? also need to capture the func parameter args. So we wrap it with another function.Because the function is a class citizen, we can define the function inside the function. This is the most commonly used form of definition for adorners, in the following form1 def Deco (func): 2 def Newfunc (*args, * *Kwargs) :3 func (*args, * *Kwargs )4 returnWhere *args, **kwargs is used to capture parameters.We need to output the information before and after the funct

Since python2.6, a new function Str.format () that formats the string has been added to the power. So, what's the advantage of being compared to the previous% format string? Let us uncover the veil of its shy.GrammarIt replaces% with {} and:.Map sampleBy location字符串的format函数可以接受不限个参数，位置可以不按顺序，可以不用或者用多次，不过2.6不能为空{}，2.7才可以。通过关键字参数通过对象属性通过下标有了这些便捷的“映射”方式，我们就有了偷懒利器。基本的Python知识告诉我们，list和tuple可以通过“打散”成普通参数给函数，而dict可以打散成关键字参数给函数（通过和*）。所以可以轻松的传个list/tuple/dict给format函数。非常灵活。Format qualifierIt has a rich

the PDB module to set breakpoints in the script to debug the script, just like this: Import PDBPdb.set_trace () You can add pdb.set_trace () anywhere in the script, and the function will set a breakpoint in that position. Super convenient. You should read more about the PDB function, because there are a lot of little-known features in it. Simplifying If structure If you must check some values, you can use the if n in [1,4,5,6]: Rather than using a complex if structure: If N==1 or n==4 or
