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')
