### Python: Setup and Basic Operations with Boto3 SDK

Source: https://beget.com/ru/kb/faq/cloud/podklyuchenie-k-obektnomu-hranilishchu-s3-pri-pomoshchi-klientov-aws-cli-s3cmd-cyberduck-sdk

This snippet demonstrates the setup process for the boto3 SDK, including creating a project directory, setting up a virtual environment, and installing the library. It then provides examples for uploading objects from a string and a file, listing objects in a bucket, and retrieving an object's content. Proper authorization configuration is required before running the code.

```bash
mkdir pyboto3
cd pyboto3
python3 -m venv .venv
source .venv/bin/activate
python -m pip install boto3
```

```python
#!/usr/bin/env python
#-*- coding: utf-8 -*-
import boto3
session = boto3.session.Session()
s3 = session.client(
    service_name='s3',
)
bucket_name = 'название_бакета'

# Загрузить объекты в бакет

## Из строки
s3.put_object(Bucket=bucket_name, Key='object_name', Body='TEST')

## Из файла
s3.upload_file('main.py', bucket_name, 'py_script.py')
s3.upload_file('main.py', bucket_name, 'script/py_script.py')

# Получить список объектов в бакете
for key in s3.list_objects(Bucket=bucket_name)['Contents']:
    print(key['Key'])

# Удалить несколько объектов
# forDeletion = [{'Key':'object_name'}, {'Key':'script/py_script.py'}]
# response = s3.delete_objects(Bucket='bucket-name', Delete={'Objects': forDeletion})

# Получить объект
get_object_response = s3.get_object(Bucket=bucket_name,Key='py_script.py')
print(get_object_response['Body'].read())
```
