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))
```
