How to insert a space between characters of all the elements of a given NumPy array?

In this article, we will discuss how to insert a space between the characters of all elements of a given array of string.
Example:
Suppose we have an array of string as follows:
A = ["geeks", "for", "geeks"]
then when we insert a space between the characters
of all elements of the above array we get the
following output.
A = ["g e e k s", "f o r", "g e e k s"]
To do this we will use np.char.join(). This method basically returns a string in which the individual characters are joined by separator character that is specified in the method. Here the separator character used is space.
Syntax: np.char.join(sep, string)
Parameters:
sep: is any specified separator
string: is any specified string.
Example:
Python3
import numpy as np
x = np.array(["geeks", "for", "geeks"],
dtype=np.str)
print("Printing the Original Array:")
print(x)
r = np.char.join(" ", x)
print("Printing the array after inserting space\
between the elements")
print(r)
|
Output:
Printing the Original Array:
['geeks' 'for' 'geeks']
Printing the array after inserting spacebetween the elements
['g e e k s' 'f o r' 'g e e k s']
