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!
