How to dynamically access class properties in Python?

Question

Let\'s say I create an instance of a class and want to assign some values to its public properties. Usually, this would be done like this:

class MyClass:
            


        

Answer 1

Using dir with setattr should do the job

class MyClass:
  def __init__(self):
    self.name = None
    self.text = None

myclass = MyClass()
myclass.name = 'My name'

for prop in dir(myclass):
    print '%s:%s'%(prop,getattr(myclass,prop))

print

for prop in dir(myclass):
    if prop[:2]!='__' and prop[-2:]!='__':
        print prop[-2:]
        setattr(myclass,prop,"Foo Bar")

for prop in dir(myclass):
    print '%s:%s'%(prop,getattr(myclass,prop))    

But be careful because this code also sets '__doc__', '__init__', '__module__' properties to "Foo Bar". So you will have to take care of avoiding certain things given to you by dir (especially those which start and end with __ double underscores).
