Grouping in Pandas
Grouping in pandas
involves dividing a DataFrame into groups based on the values in one or more columns. You can then apply a function to each group to compute a summary statistic, such as the mean, sum, or count.
To group a DataFrame in pandas
, use the .groupby()
method. This method accepts a column name or a list of column names and returns a groupby
object.
Here is an example:
This example demonstrates how to calculate the mean for each group formed based on the values in 'column_name'.
Завдання
- Group the
data
DataFrame by'DEPARTMENT_NAME'
and compute the mean, minimum, and maximum of the'MANAGER_ID'
column for each group.
