Python Work Around For 'Goto' -

-

at moment have check see if string has specific characters in it.

i trying find work around 'goto' function.

this have @ moment:

chars = set('0123456789$,')  if any((c in chars) c in userinputamount):     print 'input accepted' else:     print 'invalid entry. please try again'

i need python go string input of 'userinputamount' if entry invalid. push in right direction appreciate.

you don't need goto, need loop. try this, loops forever unless user provides valid input:

chars = set('0123456789$,')  while true: # loop "forever"     userinputamount = raw_input() # input user      if any((c in chars) c in userinputamount):         print 'input accepted'         break # exit loop      else:         print 'invalid entry. please try again'         # input wasn't valid, go 'round loop again

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.

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...
