#3514 [Core feature] Possibility to check for `None` values Issue created by MartinTschechne Motivation: Why do you think this is important? Additionally to

is_true()

and

is_false()

it would be nice to have a functionality to check whether

None

is returned by a task. This could be useful in conditionals for example. Goal: What should the final outcome look like, ideally? The function

is_none()

should simply return

True

or

False

and logically work like

if val is None:
    return True
else:
    return False

Describe alternatives you've considered Either returning the string

'None'

or

False

and explicitly check for that. Propose: Link/Inline OR Additional context No response Are you sure this issue hasn't been raised already? ☑︎ Yes Have you read the Code of Conduct? ☑︎ Yes flyteorg/flyte
