this question has answer here: can add new statements python's syntax? 13 answers mini-languages in python 6 answers normally, python calls functions by func(arg0, arg1) but change to func arg0 arg1 for example, #something... cmd = input() interpret(cmd) #something... if input 'func arg0 arg1' , expect python execute func(arg0, arg1) . args contain string, can't split words. actually, write scripts use on mobile. little annoying type parentheses. you can : class tryclass: def callfunction(self, arg, arg2): print("in call") print(arg) print(arg2) input = str(input()) input = input.split(" ") funcname = input[0] my_cls = tryclass() method = getattr(my_cls, funcname) method(input[1], inpu

i making application client sends message server , waits 5 seconds (lets assume) server respond , if there no return message, retries again. if server responds message client process it. goes on in loop , again happens after sometime. for purpose thinking use setsotimeout(time) on client socket after reading javadoc , lot of explanations on internet confused whether approach right. what read on internet (1) if use setsotimeout on socket gives timeout duration in connection needs established , if not established retries establish connection given time. (2) if use setsotimeout on socket waits incoming messages specified time interval , if no message received stops waiting. my questions - (1) of above true ? (2) if second statement true, can use implementation ? (3) if second statement true, when timeout timer kickoff ? when declare socket , set timeout period on or when send message ? if either of explanation don't apply case should wait fixed interval

how colon , semicolon differs in following linux commands? i: i; in case doesn't matter much. usually, ; used mark end of command in situations: if [[ ... ]]; ...; else ...; fi the who command, however, produce same output regardless of 2 words on command line is. : not special: $ $ makes dinner $ ano.l::e se=el these produce exact same output. so, answer question: the : part of word i: , doesn't mean special here. the semicolon marks end of command, , not needed since there no other command on line after it.
