Write a NumPy program to make the length of each element 15 of a given array and the string centered / left-justified / right-justified with paddings of _

import numpy as np
x = np.array(['python exercises', 'PHP', 'java', 'C++'], dtype=np.str)
print("Original Array:")
print(x)
centered = np.char.center(x, 15, fillchar='_')
left = np.char.ljust(x, 15, fillchar='_')
right = np.char.rjust(x, 15, fillchar='_')
print("\nCentered =", centered)
print("Left =", left)
print("Right =", right)

Sample Input:

(['python exercises', 'PHP', 'java', 'C++'], dtype=np.str)

Sample Output:

Original Array:
['python exercises' 'PHP' 'java' 'C++']

Centered = ['python exercise' '______PHP______' '______java_____' '______C++______']
Left = ['python exercise' 'PHP____________' 'java___________' 'C++____________']
Right = ['python exercise' '____________PHP' '___________java' '____________C++']
