NumPy: Repeat all the elements three times of a given array of string

NumPy String: Exercise-2 with Solution

Write a NumPy program to repeat all the elements three times of a given array of string.

Sample Solution:-

Python Code:

import numpy as np
x1 = np.array(['Python', 'PHP', 'Java', 'C++'], dtype=np.str)
print("Original Array:")
print(x1)
new_array = np.char.multiply(x1, 3)
print("New array:")
print(new_array)

Sample Input:

(['Python', 'PHP', 'Java', 'C++'], dtype=np.str)

Sample Output:

Original Array:
['Python' 'PHP' 'Java' 'C++']
New array:
['PythonPythonPython' 'PHPPHPPHP' 'JavaJavaJava' 'C++C++C++']

Debug With the Print() Function:

>>> for i in range(5):
...     print(i, end=', ' if i < 4 else '\n')
... 
0, 1, 2, 3, 4
>>> for i in range(5):
...     print(f'{i} & {i*i}', end=', ' if i < 4 else '\n')
... 
0 & 0, 1 & 1, 2 & 4, 3 & 9, 4 & 16
