1.0.2

AWS Python SDK

Simple wrapper for AWS boto3 SDK commonly used functions.

Features

• 📦 S3 operations (read, write, copy, list, delete, signed URLs)
• 🔐 SSM Parameter Store integration
• ⚡ Lambda function invocation (async and sync)
• 🚀 Optimized for AWS Lambda and serverless environments

Installation

pip install actvalue.aws-pysdk

Or with uv:

uv add actvalue.aws-pysdk

Configuration

Provide the following environment variables:

• ENV: development | production | ...
• AWSPROFILE: A named profile (non-default) in the credential file, e.g.: myprofile
• AWSREGION: A region name, e.g.: eu-west-1

Note: AWSPROFILE and AWSREGION are needed in development only. Production uses the default session/client configuration.

Usage

S3 Operations

from aws_pysdk import s3_write, s3_read, s3_read_to_string, s3_get_signed_url
import os

# Write to S3
s3_write('my-bucket', 'hello.txt', 'Hello World', 'text/plain')

# Read from S3
response = s3_read('my-bucket', 'hello.txt')
content = response['Body'].read()

# Read directly to string
content_str = s3_read_to_string('my-bucket', 'hello.txt')

# Get signed URL for reading
read_url = s3_get_signed_url(
    {'Bucket': 'my-bucket', 'Key': 'file.txt'},
    'READ',
    3600  # expires in 1 hour
)

# Get signed URL for writing
write_url = s3_get_signed_url(
    {'Bucket': 'my-bucket', 'Key': 'file.txt', 'ContentType': 'text/plain'},
    'WRITE',
    3600
)

SSM Parameter Store

from aws_pysdk import ssm_load_parameters
import os

# Define parameters to load
params = [
    {'name': '/app/bucket/name', 'env_var_name': 'MY_BUCKET', 'decrypt': False},
    {'name': '/app/api/key', 'env_var_name': 'API_KEY', 'decrypt': True},
]

# Load parameters into environment variables
ssm_load_parameters(params)

# Access loaded parameters
my_bucket = os.environ['MY_BUCKET']
api_key = os.environ['API_KEY']

Lambda Function Invocation

from aws_pysdk import lambda_invoke, lambda_invoke_with_response

# Asynchronous invocation (fire and forget)
lambda_invoke('my-function', {'key': 'value'})

# Synchronous invocation (wait for response)
result = lambda_invoke_with_response('my-function', {'key': 'value'})
print(result)  # Parsed JSON response

# Invoke with ARN
lambda_invoke_with_response(
    'arn:aws:lambda:region:account:function:my-function',
    {'data': 'payload'}
)
