The get_dummies() method returns a DataFrame where the value in the input becomes a separate column filled with binary values (1s and 0s), indicating the presence or absence of that value in each row of the original data. Example 1: Grouping by a Single Column in Pandas import pandas as...
This is useful when you have data that has missing values, and you want to encode that information about missing values in your new dummy variables. Sometimes, this is useful. In machine learning, we sometimes call this “informative missingness.” Frequently asked questions about Pandas Getdummie...

We have several methods to handle missing values but for that, we need to know how many features have the missing value. To check missing values pandas has a method named isnull(). We will sum up all the missing values of features so that we get an idea about how many features ...
