In this tutorial, we will learn the Python pandas DataFrame.compare() method. This method compares one DataFrame to another DataFrame and shows the differences. It returns the DataFrame that shows the differences stacked side by side and the resulting index will be a MultiIndex with ‘self’ and...

To check if a column is sorted in descending order, we will check if all the elements in the output array of thediff()function are less than or equal to 0. For this, we will use the comparison operator and theall()method. When we use the comparison operator on a numpy array, we ...
