<bot>: Here is a Python code to iterate an nest dict and return a return value

import pandas as pd

def iterate_nest_dict(d):
  """
  Iterate an nest dict and return
  :param d:
  :return:
  """
  for k, v in list(d.items()):
    if isinstance(v, dict):
      for k2, v2 in iterate_nest_dict(v):
        yield k, k2, v2
    else:
      yield k, v

# Enter the dict
d = {"a": {"b": 1, "c": 2}, "d": 3}

# Calling the function
print((next(iterate_nest_dict(d))))

#Example Output
# ('a', 'b', 1)

#Remember to inspect code for bugs.
