Hello I define a class person as following:
class Person(object):
def __init__(self, X, Y):
self.name = X
self.city = Y
names = ['Bob', 'Alex', 'John']
cities = ['New York', 'London', 'Rome']
N = list()
for i in range(0,3):
x = names[i]
y = cities[i]
N.append(Person(x,y))
I want to to check the corresponding cities of a name automatically, something like this
N.name['Bob'].city =
'New York'
Create a dictionary with name as key:
class Person(object):
def __init__(self, name, city):
self.name = name
self.city = city
names = ['Bob', 'Alex', 'John']
cities = ['New York', 'London', 'Rome']
persons = {n: Person(n,c) for n,c in zip(names, cities)}
print(persons['Bob'].city)
Use python dictionaries
people = {}
names = ['Bob', 'Alex', 'John']
cities = ['New York', 'London', 'Rome']
if len(names) != len(cities):
# You might want to do something other than a base exception call here
raise Exception('names and cities must be of equal size')
for i in range(len(names)):
people[names[i]] = cities[i]
print(people['Bob'])
>>>'New York'
