Dear All,  
Help me to crack this logic.

I’m not getting family types in order like series. Is there any way to get all family types in order.

Thanks in advance.

Below I attached my graph for reference.

Hi @rajkumar.kolli93 ,  
I think Natural Sort can help you here.

```
import re
tokenize = re.compile(r'(\d+)|(\D+)').findall

def natural_sortkey(string):          
    return tuple(int(num) if num else alpha for num, alpha in tokenize(string))

OUT = sorted(IN[0], key=natural_sortkey)

```

Hi @rajkumar.kolli93 ,

The last node from the solution of @AmolShah sorts the list with “Family…” so it matches the list with your codes.  
If you only want to extract the numbers i would suggest splitting your names by “-”.

```
import re
tokenize = re.compile(r'(\d+)').findall

splitText = [i.split("-")[1] for i in IN[0]]

def natural_sortkey(string):          
    return tuple(int(num) for num in tokenize(string))

OUT = splitText,sorted(splitText, key=natural_sortkey)
