 # Procedural, Object-Oriented & Functional Programming
 
-TBW
+There are generally three styles of code found in Python:
+
+**Procedural**
+
+```python
+
+point1 = (0, 5)
+point2 = (8, 3)
+point3 = (1, 7)
+
+points = [point1, point2, point3]
+
+for point in points:
+    print(sqrt(point.x ** 2 + point.y ** 2))
+
+```
+
+**Object Oriented**
+
+```python
+class Point:
+
+    def __init__(self, x, y):
+        self.x = x
+        self.y = y
+
+    def __eq__(self):
+        pass
+
+    def __hash__(self):
+        pass
+
+    def __str__(self):
+        pass
+```
+
+**Functional**
+
+```python
+point1 = (0, 5)
+point2 = (8, 3)
+point3 = (1, 7)
+
+points = [point1, point2, point3]
+
+shortest_distance = min((sqrt(point.x ** 2 +  point.y ** 2)) for point in points)
+largest_distance = max((sqrt(point.x ** 2 +  point.y ** 2)) for point in points)
+average_distance = sum((sqrt(point.x ** 2 +  point.y ** 2)) for point in points) / len(points)
+```
+
+Of course... we should clean it up...
+
+```python
+points = [(0, 5), (8, 3), (1, 7)]
+
+distances = [sqrt(point.x ** 2 +  point.y ** 2) for point in points]
+
+shortest_distance = min(distances)
+largest_distance  = max(distances)
+average_distance  = sum(distances) / len(points)
+```
+
+None of these examples are particuarly well written...
+
+  1. No `__main__`
+  2. No documentation
+  3. Everything is in `"main"`
