We can create a Pandas pivot table with multiple columns and return reshaped DataFrame. By manipulating given index or column values we can reshape the
To find unique values in multiple columns, we will use the pandas.unique() method. This method traverses over DataFrame columns and returns those values whose occurrence is not more than 1 or we can say that whose occurrence is 1.Syntax:pandas.unique(values) # or df['col'].unique() ...
Use therename()Function to Rename Multiple Columns Using Pandas The Pandas library provides therename()function used to rename the columns of a DataFrame. Therename()function takes amapper, a dictionary-like data structure that contains the renaming column as the key and the name as the value....

In Pandas DataFrame, it is possible to group multiple columns using the pandas.DataFrame.groupby function. In this guide, we will discuss how to group multiple columns in the Pandas DataFrame. We also utilize the agg()/aggregate() function along with the group by to perform the aggregation op...
