numpy字符串操作not_equal()函数

numpy.core.defchararray.not_equal(arr1, arr2) 是另一个在numpy中进行字符串操作的函数。它逐一检查两个相同形状的数组的元素，如果它们不相等则返回True。否则，它返回False。

参数:
arr1 : 类似于str或unicode的数组。
arr2 : 类似于str或unicode的数组。
返回： [ndarray] 输出布尔数组，如果arr1和arr2是标量，则输出单个布尔。

代码#1：

# Python program explaining
# numpy.char.not_equal() method
 
# importing numpy
import numpy as geek
 
# input arrays 
in_arr1 = geek.array('numpy')
print ("1st Input array : ", in_arr1)
 
in_arr2 = geek.array('numpy')
print ("2nd Input array : ", in_arr2) 
 
# checking if they are not equal
out_arr = geek.char.not_equal(in_arr1, in_arr2)
print ("Output array: ", out_arr)

输出:

1st Input array :  numpy
2nd Input array :  nump
Output array:  True

代码#2：

# Python program explaining
# numpy.char.not_equal() method
 
# importing numpy
import numpy as geek
 
# input arrays 
in_arr1 = geek.array(['Geeks', 'for', 'Geeks'])
print ("1st Input array : ", in_arr1)
 
in_arr2 = geek.array(['Geek', 'for', 'Geek'])
print ("2nd Input array : ", in_arr2)
 
# checking if they are not equal
out_arr = geek.char.not_equal(in_arr1, in_arr2)
print ("Output array: ", out_arr)

输出:

1st Input array :  ['Geeks' 'for' 'Geeks']
2nd Input array :  ['Geek' 'for' 'Geek']
Output array:  [ True False  True]

代码#3:

# Python program explaining
# numpy.char.not_equal() method
 
# importing numpy
import numpy as geek
 
# input arrays 
in_arr1 = geek.array(['10', '11', '12'])
print ("1st Input array : ", in_arr1)
 
in_arr2 = geek.array(['10', '11', '121'])
print ("2nd Input array : ", in_arr2)
 
 
# checking if they are not equal
out_arr = geek.char.not_equal(in_arr1, in_arr2)
print ("Output array: ", out_arr)

输出:

1st Input array :  ['10' '11' '12']
2nd Input array :  ['10' '11' '121']
Output array:  [False False  True]
