having foo(bar1(), bar2()) can sure in sml evaluate bar1() first , after bar2() ? yes. strictly speaking have function applied tuple. fields of tuple evaluated left right bar1() evaluated before bar2() . see "the definition of standard ml (revised)" milner, tofte, harper , macqueen page 41. note if foo expression have side-effects or raise exception evaluated before argument , therefore before either bar1() or bar2() . particularly has implications curried applications. foo (bar1()) (bar2()) will evaluate first bar1() foo(bar1value) before evaluating bar2() .

is there way perform sub on 1 character of matching pattern? for example, if have string "this word. word. h.e. stein" and want perform sub on '.'s @ end of sentence becomes "this word word h.e. stein" how should go doing this? you don't need use regular expression: >>> "qwerty.".replace('.', '', 1) # 1 -> replace count (only once) 'qwerty' to delete last character, use slice: >>> "qwerty."[:-1] 'qwerty' update according question edit. >>> text = "this word. word. h.e. stein" >>> re.sub(r'(\w{2})\.', r'\1', text) 'this word word h.e. stein' (\w{2})\. : match period after 2 word characters. capture word characters group 1. later referenced \1 .

before read on, know i'm new python , new threading forgive me if misunderstand how threads work or make rookie error :p short description of goal: the main thread (a) things (e.g. prints "begin!") main thread spawns new thread (b) first prints "thread b started" , prints x+1 forever (1, 2, 3 ...) main thread prints "woop!" then end of main thread reached, terminates , switches thread b making b main thread program running thread b main thread printing x+1 forever , has been forgotten , no longer relevant ctrl+c terminate thread b , effectively, whole program terminated because thread doesn't exist anymore here's have far (the basics): import threading, time def printcount(): print "thread b started" x = 0 while true: time.sleep(1) x = x + 1 print x ## user code ## print "begin!" threadb = threading.thread(target=printcount) threadb.start() print "woop!" th...
