Python Code :

``````from collections import Counter
color1 = ["red", "orange", "green", "blue", "white"]
color2 = ["black", "yellow", "green", "blue"]
counter1 = Counter(color1)
counter2 = Counter(color2)
print("Color1-Color2: ",list(counter1 - counter2))
print("Color2-Color1: ",list(counter2 - counter1))
```
```

Sample Output:

```Color1-Color2:  ['red', 'white', 'orange']
Color2-Color1:  ['black', 'yellow']

## Python: Tips of the Day

Floor Division:

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.

For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.

```print(1000 // 300)
print(1000 / 300)```

Output:

```3
3.3333333333333335```
