```python
|
|
|
|
class Student:
|
|
|
|
def __init__(self, name, age):
|
|
|
|
self.name = name
|
|

self.age = age

### Naming conventions
|
|
|
|
* Class names should be came lcase: ```MyClassName```
|
|
|
|
* Function/Method/Variable names should be snake case: ```my_function_name```
|
|
|
|
|
|
|
|
**see also the [PEP-8](https://www.python.org/dev/peps/pep-0008/) Python style guide**
|
|
|
|
|
|
|
|
### The ```__init__```
|
|
|
|
* function is called as soon as the class is instantiated (you create an object of it)
|
|
|
|
* all * self-variables* should be initiated here
|
|
