Groupby in Pandas can help us to split data into group and apply a statistical function to each of the group in order to analyse our data in a meaningful sense.
When we refer Groupby, it mainly involves one or more of the following steps:
Splitting: we split data into group by applying some conditions on datasets.
Applying : we apply a function to each group independently
Combining : we combine different datasets after applying groupby and results into a data structure
