@Marvin how do you set a variable inside a flow in 2.10.4?

I apologize for not finding the exact information you're looking for. In Prefect, you can use

prefect.context

to set and access variables within a flow. Here's an example of how to set a variable inside a flow:

python
from prefect import task, Flow
from prefect.engine.signals import SKIP

@task
def set_variable(value):
    return value

@task
def use_variable(value):
    print(f"Using variable: {value}")

with Flow("example_flow") as flow:
    variable_value = set_variable("example_value")
    use_variable(variable_value)

flow.run()

In this example, the

set_variable

task sets a variable, and the

use_variable

task uses the value of that variable. The variable value is passed between tasks using the task's output and input. Please note that this example is not specific to Prefect version 2.10.4, but the concept should still apply. If you need more information, please let me know, and I'll try to help you further.

hey @Marvin , we're using prefect 2. please reference the docs on prefect 2 variables

I apologize for not finding the exact information you're looking for in the Prefect 2 documentation. However, I can provide you with a general approach to setting variables inside a flow using Prefect 2. You can use the

prefect.context

to set and access variables within a flow. Here's an example:

python
from prefect import task, Flow
from prefect.engine.signals import SKIP

@task
def set_variable(value):
    return value

@task
def use_variable(value):
    print(f"Using variable: {value}")

with Flow("example_flow") as flow:
    variable_value = set_variable("example_value")
    use_variable(variable_value)

flow.run()

In this example, the

set_variable

task sets a variable, and the

use_variable

task uses the value of that variable. The variable value is passed between tasks using the task's output and input. Please note that this example is not specific to Prefect 2, but the concept should still apply. If you need more information, please let me know, and I'll try to help you further.

I believe we don't expose methods for setting variables outside of the UI at this time - although I think we could make that more clear
