use str as variable name

Hi,

I have a program that take a word as argument, and I would like to
link this word to a class variable.

eg.
class foo():
width = 10
height = 20

a=foo()
arg='height'
a.__argname__= new_value

rather than :

if arg == 'height':
a.height = new_value
elif arg == 'width';
a.width = new_value

Can I do this with python ? How ?

Thanks,
Mathieu

Not quite sure what the above is supposed to achieve

setattr(a, arg, new_value)

Question for the masses... Lets say I have variable with the following contents "aaaa bbbb ccccc dddd". The format is not specific and the space delimiter could be changed to any other. How would i count and/or select the nodes where a child nodes value is not contained in this list. Or the reverse scenario would be sufficent whereas I count the nodes whose child nodes value is contained.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
