Suppose I have a python object x and a string s, how do I set the attribute s on x? So: x SomeObject() attr 'myAttr magic goes here x. myAttr 'magic' What's the magic? The goal of this, incidentally, is to cache calls to x. getattr().
When an attribute is not found there, and the instances class has an attribute by that name, the search continues with the class attributes. by defining methods with special names. This is Pythons approach to operator overloading, allowing classes to define Once we know how to check if an object has an attribute in Python, the next step is to get that attribute. In Python, besides the normal dotstyle attribute access, there's a builtin function, getattr, which is also very useful for accessing an attribute.python class attribute name Objectoriented programming in Python: instance attributes vs. class attributes and their proper usage.
