Keys are used to add, update and retrieve JSON objects in your
dataset collection. Individual keys must be unique. But how do you know
what keys are in the collection? Use the keys()
method.
= "characters.ds"
c_name = dataset.keys(c_name) keys
Keys would now have all the keys in the collection named
“characters.ds”. It is important to know that keys just returns the
whole list. If you want a sorted list or a filtered list then you’ll
want to use the key_filter()
and key_sort()
methods.
