Dada una array numpy, la tarea es verificar si la array numpy contiene todos los ceros o no. Analicemos algunas formas de resolver la tarea anterior.
Método #1: Obtener el conteo de ceros usandonumpy.count_nonzero()
Python3
# Python code to demonstrate
# to count the number of elements
# in numpy which are zero
import numpy as np
ini_array1 = np.array([1, 2, 3, 4, 5, 6, 0])
ini_array2 = np.array([0, 0, 0, 0, 0, 0])
# printing initial arrays
print("initial arrays", ini_array1)
print(ini_array2)
# code to find whether all elements are zero
countzero_in1 = np.count_nonzero(ini_array1)
countzero_in2 = np.count_nonzero(ini_array2)
# printing result
print("Number of non-zeroes in array1 : ", countzero_in1)
print("Number of non-zeroes in array2 : ", countzero_in2)
Producción:
initial arrays [1 2 3 4 5 6 0] [0 0 0 0 0 0] Number of non-zeroes in array1 : 6 Number of non-zeroes in array2 : 0
Método #2: Usarnumpy.any()
Python3
# Python code to check that whether
# all elements in numpy are zero
import numpy as np
ini_array1 = np.array([1, 2, 3, 4, 5, 6, 0])
ini_array2 = np.array([0, 0, 0, 0, 0, 0])
# printing initial arrays
print("initial arrays", ini_array1)
# code to find whether all elements are zero
countzero_in1 = not np.any(ini_array1)
countzero_in2 = not np.any(ini_array2)
# printing result
print("Whole array contains zeroes in array1 ?: ", countzero_in1)
print("Whole array contains zeroes in array2 ?: ", countzero_in2)
Producción:
initial arrays [1 2 3 4 5 6 0] Whole array contains zeroes in array1 ?: False Whole array contains zeroes in array2 ?: True
