# NumPy: Save two given arrays into a single file in compressed format and load it

## NumPy: Basic Exercise-36 with Solution

Write a NumPy program to save two given arrays into a single file in compressed format (.npz format) and load it.

Sample Solution :

Python Code :

``````import numpy as np
import os
x = np.arange(10)
y = np.arange(11, 20)
print("Original arrays:")
print(x)
print(y)
np.savez('temp_arra.npz', x=x, y=y)
print("Load arrays from the 'temp_arra.npz' file:")
x2 = data['x']
y2 = data['y']
print(x2)
print(y2)
``````

Sample Output:

```Original arrays:
[0 1 2 3 4 5 6 7 8 9]
[11 12 13 14 15 16 17 18 19]
Load arrays from the 'temp_arra.npz' file:
[0 1 2 3 4 5 6 7 8 9]
[11 12 13 14 15 16 17 18 19]
```

## Python: Tips of the Day

Checks if the given number falls within the given range.

Example:

```def tips_range(n, start, end = 0):
return start <= n <= end if end >= start else end <= n <= start
print(tips_range(2, 4, 6))
print(tips_range(4, 8))
print(tips_range(1, 3, 5))
print(tips_range(1, 3))
```

Output:

```False
True
False
True
```
