numpy 字符串运算| equal()函数

原文:https://www . geesforgeks . org/numpy-string-operations-equal-function/

numpy.core.defchararray.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,如果它们相等,则返回。否则,返回

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.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 equal
out_arr = geek.char.equal(in_arr1, in_arr2)
print ("Output array: ", out_arr) 

Output:

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

代码#2 :

# Python program explaining
# numpy.char.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 equal
out_arr = geek.char.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:  [False  True False]

代码#3 :

# Python program explaining
# numpy.char.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 equal
out_arr = geek.char.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:  [ True  True False]
