Creating an attribute using string as a name

Question

Is it possible to create an attribute where attribute name is specified by a string

E.g.

create_attribute(QtGui.QLineEdit, 'myname')
self.myname.setText = 'created!'

That is

create_attribute(QtGui.QLineEdit, 'myname')

equals to

self.myname = QtGui.QLineEdit(self)

I have already questioned similar question Creating an object using string as a name but just to realise it does not solve my second problem!

Use setattr:

setattr(self, 'myname', QtGui.QLineEdit(self))

to get the attribute, you can use getattr:

getattr(self, 'myname').setText('bla')

You can use the __setattr__() to set the attribute using string .

Example -

class CA:
    pass

c = CA()
c.__setattr__('name','value')
c.__setattr__('myname',QtGui.QLineEdit)
c.name
>> 'value'
