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?
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 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.
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.
userobject dynamically based on a string, or if you simply do not know how to access attributes at all. Please clarify.
