numpy 字符串运算| not_equal()函数
原文:https://www . geesforgeks . org/numpy-string-operations-not _ equal-function/
numpy.core.defchararray.not_equal(arr1, arr2)是 numpy 中做字符串运算的另一个函数。它逐个检查两个相同形状数组的元素，如果它们不相等，则返回真。否则，返回假。
参数: arr1 : 类似字符串或 unicode 的数组。 arr2 : 字符串或 unicode 的 array_like。
返回:【ndarray】bool 的输出数组，如果 arr1 和 arr2 是标量，则返回单个 bool。
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('nump')
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)
Output:
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)
Output:
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)
Output:
1st Input array : ['10' '11' '12']
2nd Input array : ['10' '11' '121']
Output array: [False False True]
