Repeat all the elements of a NumPy array of strings
• Last Updated : 02 Sep, 2020

Let us see how to repeat all elements of the given array of string 3 times.

Example :

Input : [‘Akash’, ‘Rohit’, ‘Ayush’, ‘Dhruv’, ‘Radhika’]

We will be using the numpy.char.multiply(a, i) method for this task.

## numpy.char.multiply(a, i)

Syntax : numpy.char.multiply(a, i)
Parameters :

• a : array of str or unicode
• i : number of times to be repeated

Returns : Array of strings

Example 1 : Repeating 3 times.

 # importing the moduleimport numpy as np  # created array of stringsarr = np.array(['Akash', 'Rohit', 'Ayush',                 'Dhruv', 'Radhika'], dtype = np.str)print("Original Array :")print(arr)  # with the help of np.char.multiply()# repeating the characters 3 timesnew_array = np.char.multiply(arr, 3)print("\nNew array :")print(new_array)

Output :

Original Array :

New array :

Example 2: Repeating 2 times.

 # importing the moduleimport numpy as np  # created array of stringsarr = np.array(['Geeks', 'for', 'Geeks'])print("Original Array :")print(arr)  # with the help of np.char.multiply()# repeating the characters 3 timesnew_array = np.char.multiply(arr, 2)print("\nNew array :")print(new_array)

Output :

Original Array :
['Geeks' 'for' 'Geeks']

New array :
['GeeksGeeks' 'forfor' 'GeeksGeeks']
