## NumPy: Basic Exercise-38 with Solution

Write a NumPy program to convert a given array into bytes, and load it as array.

Sample Solution :

Python Code :

``````import numpy as np
import os
a = np.array([1, 2, 3, 4, 5, 6])
print("Original array:")
print(a)
a_bytes = a.tostring()
a2 = np.fromstring(a_bytes, dtype=a.dtype)
print(a2)
print(np.array_equal(a, a2))
``````

Sample Output:

```Original array:
[1 2 3 4 5 6]
[1 2 3 4 5 6]
True
```

## Python: Tips of the Day

Merges two or more lists into a list of lists, combining elements from each of the input lists based on their positions

Example:

```def tips_merge(*args, fill_value=None):
max_length = max([len(lst) for lst in args])
result = []
for i in range(max_length):
result.append([
args[k][i] if i < len(args[k])
else fill_value for k in range(len(args))
])
return result
print(tips_merge(['x', 'y'], [1, 2], [True, False]))
print(tips_merge(['x'], [1, 2], [True, False]))
print(tips_merge(['x'], [1, 2], [True, False], fill_value = '_'))
```

Output:

```[['x', 1, True], ['y', 2, False]]
[['x', 1, True], [None, 2, False]]
[['x', 1, True], ['_', 2, False]]
```
