## 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
