You are the Dungeon Master for a public DnD game at your local comic shop and recently you've had some trouble keeping your players' info neat and organized so you've decided to write a bit of code to help keep them sorted!
The goal of this code is to create an array of objects that stores a player's name and contact number from a given string.
The method should return an empty array if the argument passed is an empty string or `nil`/`None`/`null`.
## Examples
```ruby 
player_manager("John Doe, 8167238327, Jane Doe, 8163723827") returns [{player: "John Doe", contact: 8167238327}, {player: "Jane Doe", contact: 8163723827}]
player_manager(nil) returns []
player_manager("") returns []
```
```python
player_manager("John Doe, 8167238327, Jane Doe, 8163723827") returns [{"player": "John Doe", "contact": 8167238327}, {"player": "Jane Doe", "contact": 8163723827}]
player_manager(None) returns []
player_manager("")   returns []
```
```
playerManager("John Doe, 8167238327, Jane Doe, 8163723827") returns [{player: "John Doe", contact: 8167238327}, {player: "Jane Doe", contact: 8163723827}]
playerManager(null) returns []
playerManager("")   returns []
```
Have at thee!
def player_manager(players):
    return [{'player': a, 'contact': int(b)} for a, b in zip(*[iter(players.split(', '))] * 2)] if players else []
def player_manager(players):
    return [{'player': a, 'contact': int(b)} for a, b in zip(*[iter(players.split(', '))] * 2)] if players else []
