How Can I Programmatically Set Object Attributes in Python?

Programmatically Setting Attributes in Python

You're faced with a task where you need to programmatically set an attribute of an object. The goal is to cache calls to the __getattr__() method of the object. To achieve this, you can utilize the setattr function.

The syntax for setattr is:

setattr(object, attribute_name, value)

Here's a practical example:

x = SomeObject()
attr = 'myAttr'
setattr(x, attr, 'magic')
assert x.myAttr == 'magic'

By using setattr, you can dynamically assign values to attributes of an object. However, it's important to note that this may not work for "pure" instances of the object class. If you're unsure about this, consider using an appropriate subclass of the object class.
