numpy.array_equiv(arr1,arr2):此邏輯函數檢查兩個數組是否具有相同的元素並且形狀一致。
形狀一致意味著它們具有相同的形狀,或者可以廣播一個輸入數組以創建與另一輸入數組相同的形狀。
參數:
arr1 : [array_like]Input array, we need to test. arr2 : [array_like]Input array, we need to test.
返回:
True, if both arrays are equivalent; otherwise False
代碼:解釋工作
# Python program explaining
# array_equiv() 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_equiv(arr1, arr2))
arr1 = np.arange(4)
arr2 = np.arange(4)
print ("\n\narr1 : ", arr1)
print ("arr2 : ", arr2)
print ("\nResult : ", np.array_equiv(arr1, arr2))
arr1 = np.arange(4)
arr2 = np.arange(5)
print ("\n\narr1 : ", arr1)
print ("arr2 : ", arr2)
print ("\nResult : ", np.array_equiv(arr1, arr2))
a = np.array_equiv([1, 2], [[1, 2, 1, 2], [1, 2, 1, 2]])
b = np.array_equiv([1, 2], [[1, 2], [1, 2]])
print ("\n\na : ", a)
print ("\nb : ", b)
輸出:
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 a : False b : True
