@Marvin Can I update a variable in my flow?

Yes, you can update a variable in your flow in Prefect. A flow in Prefect is a Python function, so you can treat variables within the scope of that function as you would in any other Python function. Here's a simplified example to illustrate updating a variable within a flow:
Copy code
python
from prefect import flow

@flow
def example_flow():
    # Define a variable
    my_variable = "original value"
    print(my_variable)  # Outputs: original value

    # Update the variable within the flow
    my_variable = "updated value"
    print(my_variable)  # Outputs: updated value

if __name__ == "__main__":
    example_flow()
In this example,
my_variable
is updated with a new value within the flow, and the new value is printed. This is just a basic illustration; depending on the complexity of your flow and the operations you need to perform, your implementation might differ. Here is a link to a more detailed Prefect code example that illustrates writing a basic flow: basic.py example. The example doesn't show variable updating explicitly, but it demonstrates the general structure of defining and running a flow with Prefect.
