在Python中将值从一个函数传递给另一个函数

Question

I am learning Python and struggling to understand on how to send multi-values to the next function after returning the value from the first function? Also is it necessary to use main() in Python to call more than one functions?

In the following code, I would want to pass both acc_name and rg_name to the function stop().

I have this following simplified code, where the logic works as expected, hence have not included that as I just want to understand the workflow of the code.

    def handle(event, context):
       #code logic
       return acc_name, rg_name
    def stop(acc_name, rg_name):
        #code logic
    return sg_id

OR

    def handle(event, context):
       #code logic
       return acc_name, rg_name
    def stop(x,y):
        #code logic
    return sg_id

    def main():
      x,y = handle(event, context)
      stop(x,y)

I am a newbiew to Python, my code might have discrepancies from the concept. Using Python 2.7

Any help would be appreciated. Thanks in advance

I'm going to assume that what you are asking is how to pass multiple arguments from functionA to functionB without storing the arguments in between the two function calls like you did in snippet two. So how to avoid:

x, y = functionA()
functionB(x, y)

This you can do by unpacking the arguments here's the docs for the feature . You do this by calling:

functionB(*functionA())

or in your case:

stop(*handle(event, context))
