Overview:
- The python library pandas provides essential data structures and methods to perform data analysis. The DataFrame class in pandas represents a 2 dimensional array.
- The rows and columns of a pandas DataFrame object can be multiplied and their product is returned as a pandas series using the prod() method .
- By default, the value for the axis parameter is 0, which calculates the product of columns.
- To have the data values of rows multiplied, use axis=1.
Example:
import pandas as pd
dataValue = [(10,11,30,44), (10,22,30,55), (10,33,30,66)] dataFrame = pd.DataFrame(data=dataValue); print("Dataset:"); print(dataFrame);
product = dataFrame.prod(); print("Product(Row-wise):"); print(product);
product = dataFrame.prod(axis=1); print("Product(Column-wise):"); print(product); |
