How to insert a space between characters of all the elements of a given NumPy array?
• Last Updated : 29 Aug, 2020

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']```
