Hi,

I wanted to store a number series in slots with separated by comma like 1,2,3,4,5,6,7,8,9 but the user can give numbers in any form like space separated(1 2 3 4 5 6 7 8 9) or dot separated(1.2…3.4.5…6…7.8.9) but I have to fill slots with comma separated numbers only. Is there any method or any other library which I can use and works better.  
Also, I want to know if there is any method that I don’t train numbers in my training data but it will be saved in slots because the length of number series is not fixed.  
P.S. Duckling won’t work here.

Actually I have used it that’s why I wrote it in P.S. duckling extract different numbers in many slots alias **number** and for my case if I use duckling there will be lots of slots like if length is 100 then do I have to use 100 slots fill? No. That’s why I said duckling won’t work here.
