Numpy string equal()用法及代碼示例


numpy.core.defchararray.equal(arr1, arr2) 是另一個在numpy中執行字符串操作的函數。它一一檢查兩個相同形狀數組的元素,如果相等,則返回True。否則,它返回False。

參數:
arr1 :str或unicode的數組。
arr2 :str或unicode的數組。

返回:[ndarray] bool的輸出數組;如果arr1和arr2是標量,則為單個bool。


代碼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) 
輸出:
1st Input array: numpy
2nd Input array: numpy
Output array: True


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


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