the goal y or n , different things based on if/elseif/else statement. problem not see y , n proper values. know doing wrong? print 'are happy final crop?' happytest = raw_input('enter y or n: ') if happytest == 'y': happy = false elif happy == 'n': padding == int(raw_input('enter crop padding:')) else: print 'not valid input' you've got 2 problems can see: elif happy == 'n': references undefined variable, happy . meant happytest . padding == int(raw_input('enter crop padding:')) tries compare padding , int(...) . meant assign. change == = .

in 1 of web services, caching result using memcached. can either cache result json or source object. if cache source object, have convert json everytime before sending result(i doing in code because i'm using json views dynamiccaly restrict few columns). if cache json string(considerably large), have return it. question is, json string consume more memory java object or bad idea cache json strings? if cache source object via memcache, has serialized , deserialized. lot of overhead. caching json object faster. two advices on this: avoid character encoding: if possible store json object byte array , not string or char array , return via httpresponse.getoutputstream(json). way bypass additional character encoding. cache whole response: if json result of rest query, event better cache complete request via caching server in front of application (e.g. varnish, nginx, apache traffic server.). put right http cache headers on , fine.

string x= "100,000" string []y=x.split(","); string z= y[0]+y[1] (give me expected result 100000) my question if x dynamic, may sometime has "2 comas". "3 comas" (1,00,000 or 1,00,00,000 ) dynamic, can used separate comas , combine string. you can replace ',' nothing instead of splitting string. in java this: s.replaceall(",",""); if want split need loop iterates on string parts , puts new string. example in java: string x= "100,000" string []parts=x.split(","); string z= ""; for(string part : parts){ z+=part; }
