Sample Solution:

Python Code:

``````import pandas as pd
print("Original Dataframe:")
print("\nSide-by-side bar plot of the diamonds DataFrame:")
diamonds.groupby('cut').mean().plot(kind='bar')
``````

Sample Output:

```Original Dataframe:
carat      cut color clarity  depth  table  price     x     y     z
0   0.23    Ideal     E     SI2   61.5   55.0    326  3.95  3.98  2.43

How to sort a Python dict by value

Example:

```x1 = {'a': 5, 'b': 7, 'c': 9, 'd': 1}

sorted(x1.items(), key=lambda x: x)
[('d', 1), ('c', 9), ('b', 7), ('a', 5)]

# Or:

import operator
print(sorted(x1.items(), key=operator.itemgetter(1)))
```

Output:

```[('d', 1), ('a', 5), ('b', 7), ('c', 9)]
```
