Is it possible to create an object from a dictionary in python in such a way that each key is an attribute of that object?
Something like this:
d = { 'name': 'Oscar', 'lastName': 'Reyes', 'age':32 }
e = Employee(d)
print e.name # Oscar
print e.age + 10 # 42
I think it would be pretty much the inverse of this question: Python dictionary from an object's fields
Setting attributes in this way is almost certainly not the best way to solve a problem. Either:
You know what all the fields should be ahead of time. In that case, you can set all the attributes explicitly. This would look like
class Employee(object):
def __init__(self, name, last_name, age):
self.name = name
self.last_name = last_name
self.age = age
d = {'name': 'Oscar', 'last_name': 'Reyes', 'age':32 }
e = Employee(**d)
print e.name # Oscar
print e.age + 10 # 42
or
You don't know what all the fields should be ahead of time. In this case, you should store the data as a dict instead of polluting an objects namespace. Attributes are for static access. This case would look like
class Employee(object):
def __init__(self, data):
self.data = data
d = {'name': 'Oscar', 'last_name': 'Reyes', 'age':32 }
e = Employee(d)
print e.data['name'] # Oscar
print e.data['age'] + 10 # 42
Another solution that is basically equivalent to case 1 is to use a collections.namedtuple. See van's answer for how to implement that.
