Simple question but since I'm new to python, comming over from php, I get a few errors on it.
I have the following simple class:
User(object)
fullName = "John Doe"
user = User()
In PHP I could do the following:
$param = 'fullName';
echo $user->$param; // return John Doe
How do I do this in python?

python
To access field or method of an object use dot .:
user = User()
print user.fullName
If a name of the field will be defined at run time, use buildin getattr function:
field_name = "fullName"
print getattr(user, field_name) # prints content of user.fullName
You can do the following:
class User(object):
fullName = "John Doe"
def __init__(self, name):
self.SName = name
def print_names(self):
print "Names: full name: '%s', name: '%s'" % (self.fullName, self.SName)
user = User('Test Name')
user.fullName # "John Doe"
user.SName # 'Test Name'
user.print_names() # will print you Names: full name: 'John Doe', name: 'Test Name'
E.g any object attributes could be retrieved using istance.
Use getattr if you have an attribute in string form:
>>> class User(object):
name = 'John'
>>> u = User()
>>> param = 'name'
>>> getattr(u, param)
'John'
Otherwise use the dot .:
>>> class User(object):
name = 'John'
>>> u = User()
>>> u.name
'John'
If you need to fetch an object's property dynamically, use the getattr() function: getattr(user, "fullName") - or to elaborate:
user = User()
property = "fullName"
name = getattr(user, property)
Otherwise just use user.fullName.
