## NumPy String: Exercise-12 with Solution

Write a NumPy program to make all the elements of a given string to a numeric string of 5 digits with zeros on its left.

Sample Solution:-

Python Code:

``````import numpy as np
x = np.array(['2', '11', '234', '1234', '12345'], dtype=np.str)
print("\nOriginal Array:")
print(x)
r = np.char.zfill(x, 5)
print("\nNumeric string of 5 digits with zeros:")
print(r)
```
```

Sample Input:

```(['2', '11', '234', '1234', '12345'], dtype=np.str)
```

Sample Output:

```Original Array:
['2' '11' '234' '1234' '12345']

Numeric string of 5 digits with zeros:
['00002' '00011' '00234' '01234' '12345']
```

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
