Python program to demonstrate the use of pandas groupby() and apply() methods with arguments # Importing pandas packageimportpandasaspd# Creating a dictionaryd={'a':[1,1,3,4,3],'b':[7,7,0,2,4],'c':[1,6,6,3,1] }#
Pandas is a powerful and widely-used open-source library for data manipulation and analysis using Python. One of its key features is the ability to group data using the groupby function by splitting a DataFrame into groups based on one or more columns and then applying various aggregation funct...
