## NumPy String: Exercise-18 with Solution

Write a NumPy program to check whether 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]
```

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
