Pandas DataFrame take() Method – Be on the Right Side of Change (original) (raw)
Preparation
Before any data manipulation can occur, two (2) new libraries will require installation.
- The Pandas library enables access to/from a DataFrame.
- The NumPy library supports multi-dimensional arrays and matrices in addition to a collection of mathematical functions.
To install these libraries, navigate to an IDE terminal. At the command prompt ($), execute the code below. For the terminal used in this example, the command prompt is a dollar sign ($). Your terminal prompt may be different.
$ pip install pandas
Hit the <Enter> key on the keyboard to start the installation process.
$ pip install numpy
Hit the <Enter> key on the keyboard to start the installation process.
If the installations were successful, a message displays in the terminal indicating the same.
Feel free to view the PyCharm installation guide for the required libraries.
Add the following code to the top of each code snippet. This snippet will allow the code in this article to run error-free.
import pandas as pd import numpy as np
The take() method returns the elements (data) across the selected axis. The indexing performs on the actual position of the DataFrame element.
🛑 Note: This method has been deprecated (since version 1.0.0).
The syntax for this method is as follows:
DataFrame.take(indices, axis=0, is_copy=None, **kwargs)
| Parameter | Description |
|---|---|
| indices | List (array) of integers that specify locations to take. |
| axis | If zero (0) or index is selected, apply to each column. Default 0.If one (1) apply to each row. |
| is_copy | As of pandas v1.0, this parameter always returns a copy. |
| **kwargs | To be compatible with numpy.take(), the take() method does not affect the output. |
For this example, the finxters.csv data saves to a DataFrame to manipulate the data.
df = pd.read_csv('finxters.csv') result = df.take([30, 31], axis=0) print(result)
- Line [1] reads in the comma-separated CSV file and saves it to
df. - Line [2] takes the 30th and 31st row of the CSV file and saves it to the
resultvariable. - Line [3] outputs the result to the terminal.
