Getting Started with Lithops

Installation

pip install lithops

Lithops is available as a Python package that can be installed with pip. It requires Python 3.6 or higher.

Configuration

Lithops needs access to your cloud provider credentials. You can configure Lithops in several ways:

  1. Using a configuration file (~/.lithops_config)
  2. Using environment variables
  3. Programmatically when creating the executor

Example Configuration File

lithops:
  backend: aws_lambda

aws:
  access_key_id: your_access_key
  secret_access_key: your_secret_key
  region: us-east-1

Your First Lithops Function

Here's a simple example to get you started with Lithops: 

from lithops import FunctionExecutor

def hello_world(name):
    return f'Hello, {name}!'

# Create a FunctionExecutor
with FunctionExecutor() as executor:
    # Execute the function
    future = executor.call_async(hello_world, 'World')
    # Get the result
    result = future.result()
    print(result)  # Prints: Hello, World!

Parallel Execution

Lithops makes it easy to execute functions in parallel: 

from lithops import FunctionExecutor

def process_data(data):
    # Some computation with the data
    return data * 2

data_list = list(range(10))

with FunctionExecutor() as executor:
    # Map the function to the data
    futures = executor.map(process_data, data_list)
    # Get all results
    results = executor.get_result()
    print(results)  # Prints: [0, 2, 4, 6, 8, 10, 12, 14, 16, 18]
