I am going through a python code which uses the hug framework as shown below:

@hug.post("/{scan_id}/files", versions=1,
          input_format=hug.input_format.multipart)
def add_files(request, scan_id: uuid):
    pass

Now the above code works fine if I do a curl request with multi part form with files.

Now I would like to reuse the same function add_files in a different place, but I noticed this part scan_id: uuid. I don't understand how an argument can be like this. Can anyone provide any insight into this syntax?
