Pandas Dataframe.dot() Method Implementations

We can also use Pandas Dataframe for using the dot() method. The dot() method multiplies each value from one DataFrame with the values from another DataFrame, and adds them together.

Syntax:

Syntax: dataframe.dot(other)

Parameters:

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

Return of Dataframe.dot()

• If other is a Series: It returns a Series representing the dot product of the DataFrame and the Series.
• If other is a DataFrame: It returns a Series representing the dot product of the DataFrame and each row of the other DataFrame.
• If other is a NumPy array or array-like: It returns a Series representing the dot product between the DataFrame and each column 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.
