An example of an AI chatbot conversation about using the groupby function in pandas.
How do I use the groupby function in pandas?
The groupby function in pandas is used to split the data into groups based on some criteria. You can then apply a function to each group independently.
Can you give me an example of how to group data by a specific column?
Sure! If you have a DataFrame df and you want to group by the 'Category' column, you can use df.groupby('Category').
What if I want to calculate the mean of each group?
You can chain the mean() function after groupby like this: df.groupby('Category').mean().
Is it possible to group by multiple columns?
Yes, you can group by multiple columns by passing a list: df.groupby(['Category', 'Subcategory']).
