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

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

Use getattr if you have an attribute in string form    gt  gt  gt  class User object          name    John    gt  gt  gt  u   User    gt  gt  gt  param    name   gt  gt  gt  getattr u  param   John    Otherwise use the dot      gt  gt  gt  class User object          name    John    gt  gt  gt  u   User    gt  gt  gt  u name  John
