NumPy: Check if each element of a given array starts with "P"

NumPy String: Exercise-18 with Solution

Write a NumPy program to check if each element of a given array starts with "P".

Sample Solution:-

Python Code:

import numpy as np
x1 = np.array(['Python', 'PHP', 'JS', 'examples', 'html'], dtype=np.str)
print("\nOriginal Array:")
print(x1)
print("Test if each element of the said array starts with 'P':")
r = np.char.startswith(x1, "P")
print(r)

Sample Input:

(['Python', 'PHP', 'JS', 'examples', 'html'], dtype=np.str)

Sample Output:

Original Array:
['Python' 'PHP' 'JS' 'examples' 'html']
Test if each element of the said array starts with 'P':
[ True  True False False False]
