numpy.array_equal () in Python



Parameters:

  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. 

Return:

 True, if both arrays have same shape and value; otherwise False 

Code: Explaining Operation

# 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 ( "Result:" , np.array_equal (arr1, arr2))

 

arr1 = np.arange ( 4 )

arr2 = np.arange ( 4 )

print ( "arr1:" , arr1)

print ( "arr2:" , arr2)

 

print ( " Result: " , np.array_equal (arr1, arr2))

 

arr1 = np.arange ( 4 )

arr2 = np.arange ( 5 )

print ( "arr1:" , arr1)

print ( "arr2:" , arr2)

 

print ( "Result:" , np.array_equal (arr1, arr2))

Output:

 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
