Re: Formatted string to object
Thankyou everyone for help last time: The following works ok when setting a wx.lib.buttons.GenBitmapTextButton's disabled bitmap in using wxpython instead of this: self.b1.SetBitmapDisabled(self.yellow) i can use this: aaa = 1 result1 = eval(self.b%s.SetBitmapDisabled(self.yellow) % aaa) result YAY! How would i to achieve this with getattr() ? getattr(locals()['parent'], aaa)??? Why would this be better as recommended in previous post here http://groups.google.com.au/group/comp.lang.python/browse_frm/thread/2529515bc85cd954/c2f080b21d668081?q=janamarnum=1#c2f080b21d668081 Any help appreciated ta -- http://mail.python.org/mailman/listinfo/python-list

Formatted string to object
Hi,
can such a thing be done somehow?
aaa = self.aaa
bbb = %s.%s % ('parent', 'bbb')
Can you use strings or %s strings like in the above or
aaa = 'string'
aaa.%s() % 'upper'
Somehow?
Thanks for taking a look at this
Regards
Janama

Looks like you want to play with the eval() function. aaa = 'hello' result = eval(aaa.%s() % 'upper') result 'HELLO' Works for your second example. May work on your first example too. -tkc -- http://mail.python.org/mailman/listinfo/python-list

aaa = 'hello'

result
'HELLO'
Using eval() or exec should be really avoided whenever possible IMHO.
This one is best done with getattr(obj, attribute_name [,default]), ie:
aaa = string
getattr(aaa, 'upper')()
'STRING'

Use the getattr() function::
class parent(object):
... class bbb(object):
... pass
...
module_ns = __import__(__name__)
getattr(getattr(module_ns, 'parent'), 'bbb')
class '__main__.bbb'
import string
getattr(getattr(module_ns, 'string'), 'upper')
function upper at 0x00B502B0
I've imported the module itself here so you can use getattr, but you
could also use globals() instead of the inner getattr() call::
getattr(globals()['parent'], 'bbb')
class '__main__.bbb'
getattr(globals()['string'], 'upper')
function upper at 0x00B502B0

Given the first line, I assume this is inside a method body, and parent
is a local var. Then the answer is:
bbb = getattr(locals()['parent'], 'bbb')
read the doc for these two functions to get more infos.

Not directly - but here again, getattr() is your friend.
