How to find the maximum "depth" of a python dictionary or JSON object? -

-

i have json string , want know maximum depth is. depth mean number of embedded keys. if 1 key 7 "children" , know other key had many, depth 8.

since types (i believe) can embed other objects arrays , other dictionaries need checked. there way check this?

i hoping achieve without external modules if not targeting python3.

note: here mean "depth"

the following dictionary:

{   "path": "/0001_anthem",   "name": "0001_anthem",   "ismovie": true,   "runtime": 3600,   "thumbnaillocation": "/thubs/test.png",   "id": 1,    "media": [     {       "path": "/0001_anthem/louvers.mp4",       "name": "louvers.mp4"     }   ] }

would have "depth" or length of 3 because farthest embedded item key/value pair (level 3) in media array (level 2), in main dictionary (level 1). not sure terminology others use, terminology think make sense.

thanks

here's 1 implementation:

def depth(x):     if type(x) dict , x:         return 1 + max(depth(x[a]) in x)     if type(x) list , x:         return 1 + max(depth(a) in x)     return 0
