## Installation

⚠️ _Requires Python 3.12 or higher_

```bash

pip install python-injection

```

## Quick start

Simply apply the decorators and the package takes care of the rest.

```python

from injection import injectable, inject, singleton

@singleton

class Printer:

    def __init__(self):

        self.history = []

    def print(self, message: str):

        self.history.append(message)

        print(message)

@injectable

class Service:

    def __init__(self, printer: Printer):

        self.printer = printer

    def hello(self):

        self.printer.print("Hello world!")

@inject

def main(service: Service):

    service.hello()

if __name__ == "__main__":

    main()

```
