haskell - Maybe "kind-of" monad in Python

Question

Trying to find a way to clean up some of my code.

So, I have something like this in my Python code:

company = None
country = None

person = Person.find(id=12345)
if person is not None: # found        
    company = Company.find(person.companyId)

    if company is not None:
         country = Country.find(company.countryId)

return (person, company, country)

Having read a tutorial on Haskell's monads (in particular Maybe), I was wondering if it's possible to write it in another way.

Answer 1

company = country = None
try:
    person  =  Person.find(id=12345)
    company = Company.find(person.companyId)
    country = Country.find(company.countryId)
except AttributeError:
    pass # `person` or `company` might be None
