# Python: Rearrange positive and negative numbers in a given array using Lambda

## Python Lambda: Exercise-12 with Solution

Write a Python program to rearrange positive and negative numbers in a given array using Lambda.

Sample Solution:

Python Code :

``````array_nums = [-1, 2, -3, 5, 7, 8, 9, -10]
print("Original arrays:")
print(array_nums)
result = sorted(array_nums, key = lambda i: 0 if i == 0 else -1 / i)
print("\nRearrange positive and negative numbers of the said array:")
print(result)
``````

Sample Output:

```Original arrays:
[-1, 2, -3, 5, 7, 8, 9, -10]

Rearrange positive and negative numbers of the said array:
[2, 5, 7, 8, 9, -10, -3, -1]
```
