## Converting Pandas Series and DataFrame Columns to NumPy Arrays

Are you familiar with Pandas and NumPy? As data analysis tools, they hold great importance in data science.

Pandas dataframes are widely used because they are easy to manipulate, clean, and visualize, while NumPy arrays are efficient when dealing with numerical calculations. These two libraries work together to help us work with data.

In this article, we’ll discuss how to convert Pandas Series to NumPy Array, as well as how to convert a DataFrame Column to NumPy Array.

## Converting a Pandas Series to NumPy Array

Pandas provides a straightforward way to create a Series. The following example creates a Pandas Series with named indexes:

``````import pandas as pd
# Create Series Object
data = pd.Series([10,20,30,40], index=['a','b','c','d'])``````

To convert a Pandas Series to NumPy Array, use the `.values` property. Here’s an example:

``````import numpy as np
# Convert Pandas Series to NumPy Array
numpy_array = data.values

print(numpy_array)``````

### The output will look like this:

``[10 20 30 40]``

## Converting a DataFrame Column to NumPy Array

To convert a specific DataFrame column to NumPy Array, access the column, and use the `.values` property. Let’s see an example:

``````import pandas as pd
import numpy as np
data = {'name': ['Emma', 'Olivia', 'Ava', 'Isabella'], 'age': [21, 22, 19, 20]}
df = pd.DataFrame(data)
# Convert a DataFrame Column to NumPy Array
numpy_array = df['age'].values

print(numpy_array)``````

### The output will look like this:

``[21 22 19 20]``

In conclusion, converting Pandas Series to NumPy Array and converting a DataFrame Column to NumPy Array are relatively simple tasks. These conversions enable us to use the power of both libraries effectively.

With Pandas, we can clean and manipulate data, and with NumPy arrays, we can efficiently analyze large sets of numerical data. Use the resources provided to continue your learning journey in the world of data science!

In this article, we discussed how to convert Pandas Series to NumPy Array and how to convert DataFrame column to NumPy Array.

Pandas dataframes and NumPy arrays are essential tools in the field of data science. By converting Pandas Series to NumPy Array and DataFrame columns to NumPy Array, we can get the best of both worlds.

Pandas can manipulate and clean data while NumPy arrays can efficiently analyze large sets of numerical data. These conversions are relatively simple and can be achieved using a few lines of code.

It’s important to continue learning about the capabilities of these tools to take advantage of their full power.
