 For users unfamiliar with OOP, we strongly encourage you to review the background material on OOP provided by the good people at [QuantEcon](https://python.quantecon.org/intro.html) (for more on them, see below) at this link: [Object Oriented Programming](https://python-programming.quantecon.org/oop_intro.html). Unlike non-OOP languages, OOP bundles together data and functions into _objects_. These can be accessed via: **_object_name.data_** and **_object_name.method_name()_**, respectively. For organizational purposes, definitions of multiple objects are stored in _modules_, which are simply files with a **_.py_** extension. Modules can be accessed in Python via:
 
-```
+```python
 import module_name as import_name
 ```
