Know the depth of a dictionary

Question

Supposing we have this dict:

d = {\'a\':1, \'b\': {\'c\':{}}}

What would be the most straightforward way of knowing the nesting depth

Answer 1

You need to create a recursive function:

>>> def depth(d):
...     if isinstance(d, dict):
...         return 1 + (max(map(depth, d.values())) if d else 0)
...     return 0
...
>>> d = {'a':1, 'b': {'c':{}}}
>>> depth(d)
