agg
Aggregate using one or more operations over the specified axis.
Function to use for aggregating the data. If a function, must either work when passed a Series or when passed to Series.apply.
Accepted combinations are:
function
string function name
list of functions and/or function names, e.g. [np.sum, 'mean']
[np.sum, 'mean']
dict of axis labels -> functions, function names or list of such.
Parameter needed for compatibility with DataFrame.
Positional arguments to pass to func.
Keyword arguments to pass to func.
The return can be:
scalar : when Series.agg is called with single function
Series : when DataFrame.agg is called with a single function
DataFrame : when DataFrame.agg is called with several functions
Return scalar, Series or DataFrame.

Notes
agg is an alias for aggregate. Use the alias.

Examples
>>> s = pd.Series([1, 2, 3, 4]) >>> s 0 1 1 2 2 3 3 4 dtype: int64
>>> s.agg('min') 1
>>> s.agg(['min', 'max']) min 1 max 4 dtype: int64
