Python 中的 numpy.array_equal()
numpy.array_equal(arr1,arr2) : 检查两个数组是否具有相同形状和元素的逻辑函数。
参数:
arr1 : [array_like]Input array or object whose elements, we need to test.
arr2 : [array_like]Input array or object whose elements, we need to test.
返回:
True, if both arrays have same shape and value; otherwise False
代码:解释工作
# Python program explaining
# array_equal() function
import numpy as np
# input
arr1 = np.arange(4)
arr2 = [7, 4, 6, 7]
print ("arr1 : ", arr1)
print ("arr2 : ", arr2)
print ("\nResult : ", np.array_equal(arr1, arr2))
arr1 = np.arange(4)
arr2 = np.arange(4)
print ("\n\narr1 : ", arr1)
print ("arr2 : ", arr2)
print ("\nResult : ", np.array_equal(arr1, arr2))
arr1 = np.arange(4)
arr2 = np.arange(5)
print ("\n\narr1 : ", arr1)
print ("arr2 : ", arr2)
print ("\nResult : ", np.array_equal(arr1, arr2))
输出:
arr1 : [0 1 2 3]
arr2 : [7, 4, 6, 7]
Result : False
arr1 : [0 1 2 3]
arr2 : [0 1 2 3]
Result : True
arr1 : [0 1 2 3]
arr2 : [0 1 2 3 4]
Result : False
