Python dictionary code -

-

so need write python code getting keys in dictionary unique values. example

my_dict = {4:3, 5:3, 6:4, 9:8}

the program should print

[6, 9]

because 3 repeated in values. not know how see if values different , how remove them there no ".remove()" dictionaries. have tried making list of keys , values, trying mutate them in way, have had no luck. thanks

count values collections.counter dict keep keys dict value equal 1 in counter dict.

my_dict = {"4":"3", "5":"3", "6":"4", "9":"8"}   collections import counter  cn = counter(my_dict.itervalues()) print([k k,v in my_dict.iteritems() if cn[v] == 1]) ['6', '9']

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
