## Python Pandas: Data Series Exercise-21 with Solution

Write a Pandas program to find the positions of numbers that are multiples of 5 of a given series.

Sample Solution :

Python Code :

``````import pandas as pd
import numpy as np
num_series = pd.Series(np.random.randint(1, 10, 9))
print("Original Series:")
print(num_series)
result = np.argwhere(num_series % 5==0)
print("Positions of numbers that are multiples of 5:")
print(result)
``````

Sample Output:

```Original Series:
0    1
1    9
2    8
3    6
4    9
5    7
6    1
7    1
8    1
dtype: int64
Positions of numbers that are multiples of 5:
[]
```

```>>> a = ('one', 'two', 'three', 'four', 'five')
>>> if 'one' in a:
...     print('The tuple contains one.')
...
The tuple contains one.
>>> b = {0: 'zero', 1: 'one', 2: 'two', 3: 'three'}
>>> if 2 in b.keys():
...     print('The dict has the key of 2.')
...
The dict has the key of 2.
