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

# importing numpy as np
import numpy as np
  
  
# creating array of string
x = np.array(["geeks", "for", "geeks"],
             dtype=np.str)
print("Printing the Original Array:")
print(x)
  
# inserting space using np.char.join()
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']
  

                                                                                      

                                                                                
                                          
                                                                                  
                                                                  
                              
                                
                                                                            Next Article

    How to split the element of a given NumPy array with spaces?                      
                          
    To split the elements of a given array with spaces we will use numpy.char.split(). It is a function for doing string operations in NumPy. It returns a list of the words in the string, using sep as the delimiter string for each element in arr. Parameters:arr : array_like of str or unicode.Input array

    The ndarray.byteswap() method swaps the bytes of the array elements. It toggles between low-endian and big-endian data representation by returning a byteswapped array, optionally swapped in-place. Note: byteswap() method does not work on arrays of strings.

    NumPy builds on (and is a successor to) the successful Numeric array object. Its goal is to create the corner-stone for a useful environment for scientific computing. NumPy provides two fundamental objects: an N-dimensional array object (ndarray) and a universal function object (ufunc). In this post

    A very popular technique used in machine learning to transform categorical data into binary values of 0 and 1 is called the one-hot encoding technique. There are various circumstances when you need to use a one-hot encoded NumPy array rather than an array of indices, thus we can convert it using the

    Sometimes we need to remove values from the source Numpy array and add them at specific indices in the target array. In NumPy, we have this flexibility, we can remove values from one array and add them to another array. We can perform this operation using numpy.put() function and it can be applied t
