Thank you Geoff for the reply. >>>How about creating a function inside protein, e.g. protein.href, that returns the proper URL? Let me try this method also.
>>>(If that trailing star is necessary, you could also have a function to generate that, e.g. protein.starname.) Yes. The trailing star is necessary. To display to the users it is a mutant protein. I will use protein.starname. I use the below sort function to sort the object. Source: https://stackoverflow.com/a/58925845 def alphanumeric_sort(objects_list, sort_key): """ Sort a list of objects by a given key This function sort a list of objects by a given key common across the objects Sorting can be implemented on keys that are either alphabets, integers or both """ convert = lambda text: int(text) if text.isdigit() else text alphanum_key = lambda key: [ convert(c) for c in re.split("([0-9]+)", getattr(key, sort_key)) ] return sorted(objects_list, key=alphanum_key) I assume I found the issue. My mutation protein database contains greek letters also. That seems to be the problem. The rest of the data sorts well. I have to sort unicode strings also. regards Kannan On Sun, Sep 12, 2021 at 3:32 PM Geoff Kuenning <ge...@cs.hmc.edu> wrote: > How about creating a function inside protein, e.g. protein.href, that > returns the proper URL?
