Python routes non-parameter wildcards -

-

I am using the pylons and there is a problem with the termin '/' character, just, I want to ignore it . My path file looks like this: map.submapper (path_prefix = '/ app', with controller = 'app'): m.connect ('{_: /?}' As: 

 , Action = 'Index')   
 and  {_: /?}  instead of  /?  is very much like writing, since this request sets the area to do something  _ , and if I redirect, then I have to set it manually how can I get it is?  
 Thanks   
 
 
 Instead of " {_ (/?} < / Code> "or"  /?  ":  
 with  map.submapper (path_prefix = '/ app', controller = 'app') In the form of m: m.connect ('', action = 'index')

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
