Trying to get the old age level of a person from family dictionary

Question

I am trying to get the old age level of a person from this dictionary:

d = {'Sıdıka': [{'Aziz': [{'Ahmet': [{'Kuzey': []}]}, {'Öznur': [{'Elif': []}, {'Yiğit': []}]}, {'İlknur': [{'Nurullah': []}, {'Büşra': []}]}, {'İlker': [{'Melih': []}]}]}]}

"Sıdıka" is the eldest one and I want to determine her level (which is 3 (Ex. "Sıdıka" is "Kuzey"'s father's, father's, mother. Which makes 3)).

How can i achieve that?

I tried: Recursion, but couldn't figure it out how.

My attempt:

def new(self,dict,count,max):
        for i in dict:
            print(dict[i])
            if len(dict[i])!=0:
                for i in dict[i]:
                    self.new(self,i,count,max)
                    count+=1
                    print(count)
            else:
                return count

Answer 1

Here is a simple recursion in one statement (assuming d the input dictionary).

You can uncomment the print to see how it works.

def level(d, lvl=0):
    #print(f'level {lvl}:', d)
    return max((lvl, *(level(l, lvl=lvl+1)
                       for v in d.values()
                       for l in v)
               ))

level(d)

Output: 3
