pandas.Series.dot#

Series.dot(other)[source]#

Compute the dot product between the Series and the columns of other.

This method computes the dot product between the Series and anotherone, or the Series and each columns of a DataFrame, or the Series andeach columns of an array.

It can also be called usingself @ other.

Parameters:

otherSeries, DataFrame or array-like

The other object to compute the dot product with its columns.

Returns:

scalar, Series or numpy.ndarray
