Pandas Series.dot()

The dot() method is used to compute the dot product between DataFrames or Series.

Pandas Series.dot() is used to compute the dot product between DataFrames or Series. It works similarly to pd.mul() method, but instead of returning multiplied separate values, the dot product is returned (the sum of the multiplication of values at each index).

Syntax:

Syntax: Series.dot(other)

Parameters:

• other: Other Series to be used to calculate DOT product

Return of the Series.dot() function

The return of the dot function can be a scalar, series, or numpy.ndarray.

• The dot product of the Series and other if other is a Series.
• The Series of the dot product of Series and each rows of other if other is a DataFrame .
• A numpy.ndarray between the Series and each columns of the numpy array.

Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric Python packages. Pandas is one of those packages and makes importing and analyzing data much easier.
