Other Dictionary Packagesο
If youβre looking to unflatten a dictionary, such as to go from this:
{"foo.bar": "val"}
to this:
{"foo": {"bar": "val"}}
check out unflatten, flattery or morph to accomplish that.
indexed provides an OrderedDict where the values can be accessed by their index as well as by their keys.
Thereβs also python-benedict, which provides a custom dictionary with keylist/keypath support,
I/O shortcuts (Base64
, CSV
