parsing - How to write a small tokenizer in Python? -

-

this question has answer here:

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], input[2])

if put in input callfunction hello world works :)

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response
