Python中的 numpy.not_equal()

numpy.not_equal()检查两个元素是否相等。句法 ：

numpy.not_equal(x1, x2[, out])

参数 ：

x1, x2 : [array_like]Input Array whose elements we want to check
out    : [ndarray, optional]Output array that returns True/False.
    A placeholder the same shape as x1 to store the result.

返回 ：

Boolean array 

代码 1：

Python

# Python Program illustrating
# numpy.not_equal() method
  
import numpy as geek
 
a  = geek.not_equal([1., 2.], [1., 3.])
print("Not equal : \n", a, "\n")
 
b = geek.not_equal([1, 2], [[1, 3],[1, 4]])
print("Not equal : \n", b, "\n")

输出 ：

Not equal : 
 [False  True] 

Not equal : 
 [[False  True]
 [False  True]] 

代码 2：

Python

# Python Program illustrating
# numpy.not_equal() method
   
import numpy as geek
 
# Here we will compare Complex values with int
a = geek.array([0 + 1j, 2])
b = geek.array([1,2])
 
d  = geek.not_equal(a, b)
print("Comparing complex with int using .not_equal() : ", d)

输出 ：

Comparing complex with int using .not_equal() :  [ True False]

代码 3：

Python

# Python Program illustrating
# numpy.not_equal() method
   
import numpy as geek
 
# Here we will compare Float with int values
a = geek.array([1.1, 1])
b = geek.array([1, 2])
  
d  = geek.not_equal(a, b)
print("\nComparing float with int using .not_equal() : ", d)

输出 ：

Comparing float with int using .not_equal() :  [ True  True]
