Here is an example code snippet that demonstrates how to use the groupby() method in pandas to group a DataFrame by two columns and get the counts for each group:
DataFrame.shapeproperty returns the rows and columns, for rows get it from the first index which is zero; likedf.shape[0]and for columns count, you can get it fromdf.shape[1]. Alternatively, to find the number of rows that exist in a DataFrame, you can useDataFrame.count()method, but...
