Podemos averiguar la media de cada fila y columna de la array 2d usando numpy con la función np.mean() . Aquí tenemos que proporcionar el eje para encontrar la media.
Sintaxis: numpy.mean(arr, eje = Ninguno)
Para media de fila: eje = 1
Para media de columna: eje = 0
Ejemplo:
Python3
# Importing Library
import numpy as np
# creating 2d array
arr = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
# Calculating mean across Rows
row_mean = np.mean(arr, axis=1)
row1_mean = row_mean[0]
print("Mean of Row 1 is", row1_mean)
row2_mean = row_mean[1]
print("Mean of Row 2 is", row2_mean)
row3_mean = row_mean[2]
print("Mean of Row 3 is", row3_mean)
# Calculating mean across Columns
column_mean = np.mean(arr, axis=0)
column1_mean = column_mean[0]
print("Mean of column 1 is", column1_mean)
column2_mean = column_mean[1]
print("Mean of column 2 is", column2_mean)
column3_mean = column_mean[2]
print("Mean of column 3 is", column3_mean)
Producción:
Mean of Row 1 is 2.0 Mean of Row 2 is 5.0 Mean of Row 3 is 8.0 Mean of column 1 is 4.0 Mean of column 2 is 5.0 Mean of column 3 is 6.0
