How to delete instances with missing values in Python?
How to delete instances with missing values in Python?
This recipe helps you delete instances with missing values in Python
Recipe Objective
In many dataset we find missing values so how to delete missing values.
So this is the recipe on how we can delete instances with missing values in Python.
Step 1 - Importing Library
import numpy as np
We have only imported numpy which is needed.
Step 2 - Creating Array
We have created array of which we will delete missing value.
X = np.array([[1.1, 11.1],
[2.2, 22.2],
[3.3, 33.3],
[4.4, 44.4],
[np.nan, 55]])
Step 3 - Removing Missing Values
We will drop missing value by using np.isnan() and we will print it.
X = X[np.isnan(X).any(axis=1)]
print(X)
So the output comes as
[[nan 55.]]
