### Install Literal AI Python Client

Source: https://github.com/chainlit/literalai-python/blob/main/README.md

Installs the Literal AI Python client library using pip. This command adds the necessary package to your Python environment.

```bash
pip install literalai
```

--------------------------------

### Set Up Literal AI Development Environment

Source: https://github.com/chainlit/literalai-python/blob/main/README.md

Installs development dependencies for the Literal AI project. This command is typically used by contributors to set up their local development environment.

```bash
pip install -r requirements-dev.txt
```

--------------------------------

### Initialize Literal AI Client and Define Steps

Source: https://github.com/chainlit/literalai-python/blob/main/README.md

Demonstrates how to initialize the Literal AI client, load environment variables (specifically LITERAL_API_KEY from a .env file), define a custom step using a decorator, and run a thread. This example shows a basic 'Hello World' flow.

```python
from literalai import LiteralClient
from dotenv import load_dotenv

load_dotenv()

literalai_client = LiteralClient()

@literalai_client.step(type="run")
def my_step(input):
    return f"World"


@literalai_client.thread
def main():
    print(my_step("Hello"))


main()
client.flush_and_stop()
print("Done")
```

--------------------------------

### Python Project Dependencies (requirements.txt)

Source: https://github.com/chainlit/literalai-python/blob/main/requirements.txt

Specifies the required Python packages and their version constraints for the LiteralAI project. These dependencies are typically installed using pip from a `requirements.txt` file to ensure a consistent environment.

```Python
asyncio==3.4.3
packaging==23.2
httpx>=0.23.0
pydantic>=1,<3
openai>=1.0.0
chevron>=0.14.0
traceloop-sdk>=0.33.12
```

### Literal AI API Class Hierarchy Overview

Source: https://github.com/chainlit/literalai-python/blob/main/literalai/api/README.md

This entry describes the core classes for interacting with the Literal AI platform. It introduces `BaseLiteralAPI` as the foundational class containing all method prototypes, and its two inheriting classes, `LiteralAPI` for synchronous operations and `AsyncLiteralAPI` for asynchronous operations.

```APIDOC
Literal AI API Structure:
  BaseLiteralAPI:
    - Serves as the base class for all Literal AI API interactions.
    - Contains all method prototypes and is the primary source of documentation.
  LiteralAPI:
    - Inherits from BaseLiteralAPI.
    - Provides synchronous API methods.
  AsyncLiteralAPI:
    - Inherits from BaseLiteralAPI.
    - Provides asynchronous API methods.
