字符串的两个 NumPy 数组的元素串联
原文:https://www . geeksforgeeks . org/element-wise-concation-two-numpy-array-of-string/
在本文中，我们将讨论如何按元素连接两个字符串数组
示例:
Input :
A = ['Akash', 'Ayush', 'Diksha', 'Radhika']
B = ['Kumar', 'Sharma', 'Tewari', 'Pegowal']
Output :
A + B = [AkashKumar, AyushSharma, 'DikshTewari', 'RadhikaPegowal']
我们将使用 方法。
语法: numpy.char.add(x1，x2) 参数:**
- x1 : 第一个要连接的数组(开始连接)
- x2 : 第二个要串接的数组(串接在最后)
返回:字符串或 unicode 数组
例 1: 单元素字符串数组。

# importing library numpy as np
import numpy as np
# creating array as first_name
first_name = np.array(['Geeks'],
dtype = np.str)
print("Printing first name array:")
print(first_name)
# creating array as last name
last_name = np.array(['forGeeks'],
dtype = np.str)
print("Printing last name array:")
print(last_name)
# concate first_name and last_name
# into new array named as full_name
full_name = np.char.add(first_name, last_name)
print("\nPrinting concatenate array as full name:")
print(full_name)
输出:
Printing first name array:
['Geeks']
Printing last name array:
['forGeeks']
Printing concatenate array as full name:
['GeeksforGeeks']
例 2: 多元素字符串数组。

# importing library numpy as np
import numpy as np
# creating array as first_name
first_name = np.array(['Akash', 'Ayush', 'Diksha',
'Radhika'], dtype = np.str)
print("Printing first name array:")
print(first_name)
# creating array as last name
last_name = np.array(['Kumar', 'Sharma', 'Tewari',
'Pegowal'], dtype = np.str)
print("Printing last name array:")
print(last_name)
# concate first_name and last_name
# into new array named as full_name
full_name = np.char.add(first_name, last_name)
print("\nPrinting concatenate array as full name:")
print(full_name)
输出:
Printing first name array:
['Akash' 'Ayush' 'Diksha' 'Radhika']
Printing last name array:
['Kumar' 'Sharma' 'Tewari' 'Pegowal']
Printing concatenate array as full name:
['AkashKumar' 'AyushSharma' 'DikshaTewari' 'RadhikaPegowal']
