How to apply a Python timings decorator to a method within a class -

-

i trying apply timing decorator described here method within class instead of standalone method. how should done?

i getting error:

 typeerror: unbound method wrapper() must called someclass instance first argument (got float instance instead)

edit

thanks comment, think know problem is. doesn't work:

class a:      @timings     @classmethod     def a(cls, x):        print(x)  a.a(2)

for reason said. typeerror: unbound method wrapper() must called instance first argument (got int instance instead)

but does:

class a:      @classmethod     @timings     def a(cls, x):         print(x)  a.a(2)

so order matters. think what's going on here it's fooling way python handles bound methods: when python looks @ member a, has make decision:

  1. make bound method
  2. make class method
  3. do nothing (leave is)

if gets regular function, (1), , @timings produces regular function.

does solve problem?

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
