How to Yield in a recursive function in Python

Question

So I have a dictionary:

{\'a\': {\'b\': {\'c\': \'d\', \'e\': \'f\'}}}

I need to create a dictionary as follows:

{\'c\':\'d\',          


        

Answer 1

Note that you do not necessarily need to use yield:

def last(d):
  c = [i for b in d.items() for i in ([b] if not isinstance(b[-1], dict) else last(b[-1]))]
  return c

print(dict(last({'a': {'b': {'c': 'd', 'e': 'f'}}})))

Output:

{'c': 'd', 'e': 'f'}
