python pandas aggregate average

title: python pandas aggregate average: a step-by-step tutorial
pandas is a powerful data manipulation and analysis library in python. one common task when working with data is aggregating and summarizing information. in this tutorial, we will focus on using pandas to aggregate data and calculate the average using the groupby and agg functions.
before we begin, make sure you have pandas installed. you can install it using:
let's start by creating a sample dataset for demonstration purposes. in this example, we'll use a fictional sales dataset with columns 'product', 'category', and 'sales':
now, let's group the data by the 'product' and 'category' columns and calculate the average sales for each group:
here, we use the groupby method to group the dataframe by the specified columns ('product' and 'category'). then, we use the agg method to apply an aggregation function, in this case, calculating the mean (average) of the 'sales' column. the result is stored in a new dataframe, and we use reset_index() to make the grouped columns part of the dataframe again.
the output should look like this:
in this tutorial, we've covered the basics of aggregating data in pandas using the groupby and agg functions, specifically focusing on calculating the average. this is a common operation in data analysis, and understanding these pandas functions will help you efficiently analyze and summarize your data.
