Flytekit Python is the Python Library for easily authoring, testing, deploying, and interacting with Flyte tasks, workflows, and launch plans.

If you haven't explored Flyte yet, please refer to:

 - [Flyte homepage](https://flyte.org)

 - [Flyte core repository](https://github.com/flyteorg/flyte)

## 🚀 Quick Start

Flytekit is the core extensible library to author Flyte workflows and tasks and interact with Flyte backend services.

### Installation

```bash

pip install flytekit

```

### A Simple Example

```python

from flytekit import task, workflow

@task(cache=True, cache_version="1", retries=3)

def sum(x: int, y: int) -> int:

    return x + y

@task(cache=True, cache_version="1", retries=3)

def square(z: int) -> int:

    return z*z

@workflow

def my_workflow(x: int, y: int) -> int:

    return sum(x=square(z=x), y=square(z=y))

```
