- Read the guideline before start
You have a list of dicts people, every dict means
a person, it has keys: name, age,
wife/husband - depends on person is male or
female. All names are different. Key
wife/husband can be either None or
name of another person.
Create class Person. It's constructor takes
and store name, age of a person.
This class also should have a class attribute
people, it is a dict that stores Person
instances by their name. Constructor should
add elements to this attribute.
Write function create_person_list, this function
takes list people and return list with
Person instances instead of dicts.
Note:
If person's key wife/husband is not
None - create_person_list should add
attribute wife/husband respectively
to its instance. This attribute should
be a link to a Person instance with name the
same as wife/husband key in person's dict.
Example:
people = [
{"name": "Ross", "age": 30, "wife": "Rachel"},
{"name": "Joey", "age": 29, "wife": None},
{"name": "Rachel", "age": 28, "husband": "Ross"}
]
person_list = create_person_list(people)
isinstance(person_list[0], Person) # True
person_list[0].name == "Ross"
person_list[0].wife is person_list[2] # True
person_list[0].wife.name == "Rachel"
person_list[1].name == "Joey"
person_list[1].wife
# AttributeError
isinstance(person_list[2], Person) # True
person_list[2].name == "Rachel"
person_list[2].husband is person_list[0] # True
# The same as person_list[0]
person_list[2].husband.name == "Ross"
person_list[2].husband.wife is person_list[2] # True
Person.people == {
"Ross": <__main__.Person object at 0x10c20ca60>,
"Joey": <__main__.Person object at 0x10c180a00>,
"Rachel": <__main__.Person object at 0x10c1804f0>
