## Example using Python API

### 1. Prerequisites

- Install MinIO Server from [here](https://docs.min.io/community/minio-object-store/operations/deployments/baremetal-deploy-minio-on-redhat-linux.html#procedure).
- Familiarity with AWS S3 API.
- Familiarity with Python and installing dependencies.

### 2. Install boto3

Install `aws-sdk-python` from AWS SDK for Python official docs [here](https://aws.amazon.com/sdk-for-python/)

// 这里我们还没有设置环境变量
$ python main.py

// 因为我们没有设置环境变量，所以我们得到的是默认值

Hello World from Python

// 但是如果我们事先创建过一个环境变量
$ export MY_NAME="Wade Wilson"

// 然后再次调用程序
$ python main.py

// 现在就可以读取到环境变量了

Hello Wade Wilson from Python
```

Now modify the file `main.py` to receive a body from a `PUT` request.

Declare the body using standard Python types, thanks to Pydantic.
