Question
Which of the following attributes would you use to get a DataFrame as a numpy array?
Solution
You would use the .values attribute to get a DataFrame as a numpy array. Here are the steps:
- Import the necessary libraries: pandas and numpy.
import pandas as pd
import numpy as np
- Create a DataFrame.
df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]})
- Use the
.valuesattribute to convert the DataFrame to a numpy array.
array = df.values
- Print the array to verify the conversion.
print(array)
This will output:
array([[1, 4],
[2, 5],
[3, 6]])
So, the DataFrame has been successfully converted to a numpy array.
