Get Final Elements Of Nested Dictionary In Python

How do I get the latest elements of the nested dictionary by one or few keys? For example my nested dict is: { 'key_1' : { 'key_1_1' : {

Solution 1:

A simple recursive function should do what you're looking for:

def vals(x):
    if isinstance(x, dict):
        result = []
        for v in x.values():
            result.extend(vals(v))
        return result
    else:
        return [x]

used as..

>>> d = {1:2, 3:{4:5, 6:7}}
>>> vals(d)
[2, 5, 7]
>>> vals(d[1])
[2]
>>> vals(d[3])                                                                  
[5, 7]
