In NumPy, you can use functions like np.round(), np.ceil(), np.floor(), and np.trunc() to apply different rounding strategies. For pandas, the df.round() method allows rounding of entire DataFrames or specific columns.By the end of this tutorial, you’ll understand that:Python uses ...
column_name: Specify the column where you want to remove rows withNAvalues. Let’s illustrate the process with a practical example using a data frame namedDelftstack. This data frame contains columns forName,LastName,Id, andDesignation, and we aim to remove rows withNAvalues in theIdcolumn. ...
import numpy as np DIS_subset = df_boston["DIS"] print(np.where(DIS_subset > 10)) Output: These are array indexes containing data points that are outliers as defined by the above criterion. At the end of the article, we will show you how to use these indices to remove outliers fro...
