numpy.char.multiply() function in Python

The multiply() method of the char class in the NumPy module is used for element-wise string multiple concatenation.

numpy.char.multiply()

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 : Using the method on a single element string array.

Python3

# importing the module
import numpy as np

# created an array
arr1 = np.array(['Geeks'])
print("Original Array :")
print(arr1)

# number of times to be repeated
i = 3

# using the char.multiply() method
arr2 = np.char.multiply(arr1, i)
print("\nNew array :")
print(arr2)

Output :

Original Array :
['Geeks']

New array :
['GeeksGeeksGeeks']

Example 2 : Using the method on multiple elements string array.

Python3

# importing the module
import numpy as np

# created an array
arr1 = np.array(['Geeks', 'for', 'Geeks'])
print("Original Array :")
print(arr1)

# number of times to be repeated
i = 2

# using the char.multiply() method
arr2 = np.char.multiply(arr1, i)
print("\nNew array :")
print(arr2)

Output :

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

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