numpy.char.add() function in Python
The add() method of the char class in the NumPy module is used for element-wise string concatenation for two arrays of str or unicode.
numpy.char.add()
Syntax : numpy.char.add(x1, x2)
Parameters :
- x1 : first array to be concatenated (concatenated at the beginning)
- x2 : second array to be concatenated (concatenated at the end)
Returns : Array of strings or unicode
Example 1 : Using the method on 2 single element string arrays.
Python3
# importing the module import numpy as np # create the arrays x1 = ['Hello'] x2 = ['World'] print("The arrays are : ") print(x1) print(x2) # using the char.add() method result = np.char.add(x1, x2) print("\nThe concatenated array is :") print(result) |
Output :
The arrays are : ['Hello'] ['World'] The concatenated array is : ['HelloWorld']
Example 2 : Using the method on 2 multiple elements string arrays.
Python3
# importing the module import numpy as np # create the arrays x1 = ['Hello', 'to', 'all'] x2 = ['Beginner', 'for', 'Beginner'] print("The arrays are : ") print(x1) print(x2) # using the char.add() method result = np.char.add(x1, x2) print("\nThe concatenated array is :") print(result) |
Output :
The arrays are : ['Hello', 'to', 'all'] ['Beginner', 'for', 'Beginner'] The concatenated array is : ['HelloBeginner' 'tofor' 'allBeginner']
