python - Convert a list into a nested dictionary -

for illustration have

x = ['a','b','c']

i need convert to:

y['a']['b']['c'] = ''

is possible?

for background, have config file contains dotted notation points place in json data. i'd utilize dotted notation string access specific info in json file. example, in config:

path_to_data = "user.name.first_name"

i'd script recognize as:

json_data["user"]["name"]["first_name"]

so can value of first_name field. converted original string list, , don't know how convert nested dict.

edit: there existing info construction need apply dict with. let's say:

m = {'a': {'b': {'c': 'lolcat'}}}

so that

m['a']['b']['c']

gives me 'lolcat'. if right dictionary construction (as of replies did), still need apply existing dictionary 'm'.

so, again, config file:

c = 'a.b.c'

that converted list, thinking create things easier:

x = ['a','b','c']

now have json-like info structure:

m = {'a': {'b': {'c': 'lolcat'}}}

so nested dict generated 'x' should able traverse 'm' that

m['a']['b']['c']

gets me cat.

li = ['a','b','c'] d = reduce(lambda x, y: {y:x}, reversed(li+[''])) print(d) print(d['a']['b']['c'])
