in bash, possible execute command in background appending & . how can in python? while true: data = raw_input('enter something: ') requests.post(url, data=data) # don't wait finish. print('sending post request...') # should appear immediately. i use multiprocessing.dummy.pool . create singleton thread pool @ module level, , use pool.apply_async(requests.get, [params]) launch task. this command gives me future, can add list other futures indefinitely until i'd collect or of results. multiprocessing.dummy.pool is, against logic , reason, thread pool , not process pool. example (works in both python 2 , 3, long requests installed): from multiprocessing.dummy import pool import requests pool = pool(10) # creates pool ten threads; more threads = more concurrency. # "pool" module attribute; can sure there # 1 of them in application # modules cached after initializati...

i have instance of decodejson[a] particular type, a , , have instance of json , call j . i'd j.as[list[a]] . however, json coming me 3rd party, , if of items in array missing fields, i'd log errors items , collect items can parsed (instead of failing entire decoding). it seems me want end (list[(string, cursorhistory)], list[a]) . is, decoded elements end in list on right, , errors items not parsed accumulated on left. looks lot monadplus.separate method in scalaz. i can think of couple ways of getting there. 1 way like: j.as[list[json]].map(_.map(_.as[a].result).separate) this should give me decoderesult[list[(string, cursorhistory)], list[a]] desired. however, throw away cursor information in json array items failed located. use zipwithindex , starts pretty messy. to me seems better solution this: implicit def decoderesultdecodejson[a: decodejson]: decodejson[decoderesult[a]] = decodearr(_.as[a]) // outer decoderesult success j.as[list[decoderesult[a]]]....
