How can I perform advanced operations with Pandas?

You can perform advanced operations in Pandas using methods like groupby, pivot_table, and merging dataframes. What specific operation are you interested in?

Can you explain how to use groupby with multiple columns?

Sure! You can use groupby with multiple columns by passing a list of column names to the groupby method. For example: df.groupby(['col1', 'col2']).sum() will group by both col1 and col2 and then sum the values.

What about pivot tables? How do they work?

Pivot tables in Pandas can be created using the pivot_table method. You specify the index, columns, and values you want to aggregate. For example: df.pivot_table(index='col1', columns='col2', values='col3', aggfunc='mean').

Can you show me an example of merging two dataframes?

Absolutely! You can merge two dataframes using the merge function. For example: pd.merge(df1, df2, on='key_column') will merge df1 and df2 on the specified key column.
