python - Requires string as left operand, not reversed Error -


so code far: 

def mirror(s, v, m):     rev = reversed(v)     if(v in s):          if(rev in s):               if(m in s):                   return true     return false str1 = "abcmcba" str2 = "abc" str3 = "m" mirror(str1, str2, str3)

it supposed return true keeps giving me error: requires string left operand, not reversed

you can streamline function following:

def mirror(s, v, m):     return m in s , v in s , v[::-1] in s

note i've put fastest checks first doesn't waste time on slower operations unless they're necessary.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
