+A collection of facts about Python that do not fit into the main lesson
+either due to the scope or time constraints of the main lesson.
+
+## Jupyter Notebook/IPython: Who's Who in Memory
+
+You can use the `%whos` command at any time to see what
+variables you have created and what modules you have loaded into the computer's memory.
+As this is an IPython command, it will only work if you are in an IPython terminal or the
+Jupyter Notebook.
+
+```python
+%whos
+```
+
+```output
+Variable    Type       Data/Info
+--------------------------------
+weight_kg   float      100.0
+weight_lb   float      143.0
+```
+
+<br />
+## Integer Division
+
+We are using Python 3, where division always returns a floating point number:
+
+```python
+5/9
+```
+
+```output
+0.5555555555555556
+```
+
+Unfortunately, this wasn't the case in Python 2:
+
+```python
+5/9
+```
+
+```output
+0
+```
+
+If you are using Python 2 and want to keep the fractional part of division
+you need to convert one or the other number to floating point:
+
+```python
+float(5)/9
+```
+
+```output
+0.555555555556
+```
+
+```python
+5/float(9)
+```
+
+```output
+0.555555555556
+```
+
+```python
+5.0/9
+```
+
+```output
+0.555555555556
+```
+
+```python
+5/9.0
+```
+
+```output
+0.555555555556
+```
+
+And if you want an integer result from division in Python 3,
+use a double-slash:
+
+```python
+4//2
+```
+
+```output
+2
+```
+
+```python
+3//2
+```
+
+```output
+1
+```
+
+
