How to handle jobs that return values?

[saketvora]

Sorry in advance if this is already documented somewhere, can't find it yet.

I have functions that return values, and I'm struggling to see how to factor that into the way you schedule and run jobs with this library. Example, a function called getData() that does a API get request, and returns a variable called data Then a function called processData(data) that takes the data and does something with it.

In my example, I'd like to only run getData() once every 48 hours, but I need to run processData(data) every hour. (The reason for this is that the data feed via API doesn't refresh very often, so I don't need to call it every hour).

I see the syntax for defining the scheduling parameters be:

schedule.every(48).hours.do(getData)
schedule.every(1).hours.do(processData)

but how do I handle the data variable returned by getData()

All the examples I've found so far with schedule are jobs that don't return values. If I need my jobs to share data with each other, maybe I need to use global variables?

Any help much appreciated, thanks.

One way to get around of this is the function access the outer scope (such as the global scope)

getData could access a variable to update it's value, and processData could do the same to read this value. With a 'wrapper' of any kind (a dict, list or class), you can do this with less chance of messing with references.

See an example:

import schedule

class Wrapper:
    value = None

data = Wrapper()

def getData():
    print("Getting new data...")
    data.value = 'the new data'

def processData():
    print("I'm processing... current value:")
    print(data.value)

schedule.every(8).seconds.do(getData)
schedule.every(5).seconds.do(processData)

yup, this type of wrapper worked for me and it is a good thing to have. I have significantly more complex scenario with, rpc, statemachine, scheduler, and multi processing but at the end I got result of operation finally back to caller ...

thanks for the hint ...
