How do you debug in Python? Coming from a Matlab and R user. I'm already aware of pdb.

Hi Michael,
Here's the code again, class should be called PERSONDatabase, misspelled
earlier:
class PERSONDatabase:
   def __init__(self, id, created_at, name, attend_date, distance):
      self._id = id
      self.created_at = created_at
      self.name= name
      self.attend_date = attend_date
      self.distance = distance

   @classmethod
   def get_person(self, employee):
      return PERSONDatabase(employee['created_at'],
                                                employee['id'],
                                                employee['name'],
                                                employee['attend_date'],
                                                employee['distance'])

The PERSONDatabase class is called from main. This is the trace back I got
from the VS code:

Traceback (most recent call last):
   File "/Users/Mike/Documents/Mike/main.py", line 95, in <module>
      main()
   File "/Users/Mike/Documents/Mike/main.py", line 86, in main
      args = get_feed()
   File "/Users/Mike/DocumentsMike/main.py", line 32, in get_feed
      result = [PERSONatabase.get_person(raw_person) for raw_neo in
raw_objects]
   File "/Users/Mike/Documents/Mike/main.py", line 32, in <listcomp>
      result = [NEODatabase.get_person(raw_person) for raw_neo in
raw_objects]
   File "/Users/Mike/Documents/Mike/database.py", line 24, in get_person
      return PERSONDatabase(person['created_at'],
KeyError: 'created_at'

Thank you very much!
