Let's say we want to create/maintain a dict with below key structure { "a": {"bb": {"01": "some value 01", "02": "some value 02", } }, } We use dpath .new() as below to do this import dpath d=dict() ; print(d) # d={} dpath.new(d,'a/bb/00/c', '00val') ; print(d) # d={'a': {'bb': [{'c': '00val'}]}} # d # NOTE this will set :bb as a list, and set at bb[00] ie idx=0 of list bb # d # what we want instead is d={'a': {'bb': {'00': {'c': '00val'} }}} # d # what we want is NOT d={'a': {'bb': [ {'c': '00val'} ]}} So when using 00 in the path, dpath translate it into list index at 0 instead of dict key 00 The question is how to set key as 00? Currently I have to dodge it by setting prefix s ie s00 s01 s02 Continue reading...
