Python numpy.array_equal()用法及代碼示例


numpy.array_equal(arr1,arr2):此邏輯函數檢查兩個數組是否具有相同的形狀和元素。

參數:

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


代碼:解釋工作

# 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))

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
