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']
