22. Extract by Positions

Write a Pandas program to extract items at given positions of a given series.

Sample Solution :

Python Code :

import pandas as pd
num_series = pd.Series(list('2390238923902390239023'))
element_pos = [0, 2, 6, 11, 21]
print("Original Series:")
print(num_series)
result = num_series.take(element_pos)
print("\nExtract items at given positions of the said series:")
print(result)

Sample Output:

Original Series:
0     2
1     3
2     9
3     0
4     2
5     3
6     8
7     9
8     2
9     3
10    9
11    0
12    2
13    3
14    9
15    0
16    2
17    3
18    9
19    0
20    2
21    3
dtype: object

Extract items at given positions of the said series:
0     2
2     9
6     8
11    0
21    3
dtype: object

Explanation:

num_series = pd.Series(list('2390238923902390239023')): This code creates a Pandas Series object 'num_series' containing a string of digits.

element_pos = [0, 2, 6, 11, 21]: This code creates a Python list ‘element_pos’ containing the positions of the elements in the Pandas Series object 'num_series' that we want to extract. In this case, the positions are [0, 2, 6, 11, 21].

result = num_series.take(element_pos): This code creates a new Pandas Series object 'result' by extracting the elements in 'num_series' that correspond to the indices specified in the list element_pos. This is done using the .take() method, which takes a list of indices and returns a new Series object containing the elements at those indices.
