## Python Pandas: Data Series Exercise-26 with Solution

Write a Pandas program to compute difference of differences between consecutive numbers of a given series.

Sample Solution :

Python Code :

``````import pandas as pd
series1 = pd.Series([1, 3, 5, 8, 10, 11, 15])
print("Original Series:")
print(series1)
print("\nDifference of differences between consecutive numbers of the said series:")
print(series1.diff().tolist())
print(series1.diff().diff().tolist())
``````

Sample Output:

```Original Series:
0     1
1     3
2     5
3     8
4    10
5    11
6    15
dtype: int64

Difference of differences between consecutive numbers of the said series:
[nan, 2.0, 2.0, 3.0, 2.0, 1.0, 4.0]
[nan, nan, 0.0, 1.0, -1.0, -1.0, 3.0]
```

```>>> items = (0, 'b', 'one', 10,  11, 'zero')
>>> a, b, c, d, e, f = items
>>> print(f)
zero
>>> a, *b, c = items
>>> print(b)
['b', 'one', 10, 11]
>>> *_, a, b = items
>>> print(a)
11
