Get an object attribute [duplicate]

Question

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?

Answer 1

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 

Answer 2

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'
