around this issue You can just use global variables. If you need to change them within a function you can use the global keyword:
code :
s = 1
def set():
    global s
    s = 2
print(s)
set()
print(s)

> 1
> 2

like below fixes the issue As Xeno said, you need a while loop to continually loop over the input. For your case, I would suggest a do-while loop, but Python does not have a built-in do-while, so you will need to emulate one, possibly something like this:
code :
while True:
    # do stuff
    if condition:
        break
def insert(word, desc):
    # do stuff
def main_list():
    # do stuff

    while True:
        # do more stuff

        if condition:
            break

    # do more stuff

def insert():
    # do stuff - return any new value; otherwise, just let it auto-return

def look():
    # do stuff - return any new value; otherwise, just let it auto-return

around this issue The problem with your code is that you've put the function ccc inside the funciton aaa and that is not the correct way of doing what you're trying to do. The correct way would be to create a Class aaa and then declaring ccc as its method.

fixed the issue. Will look into that further As jasonharper's comment mentions, you need to use the global keyword to reference the global variable, otherwise you make a new scoped variable.
Without global:
code :
x = 3

def setToFour():
    x = 4
    print(x)

print(x)
setToFour()
print(x)
>> 3
>> 4
>> 3
x = 3

def setToFour():
    global x
    x = 4
    print(x)

print(x)
setToFour()
print(x)
>> 3
>> 4
>> 4

Any of those help Firstly, although it doesn't affect your problem there is no need to use the global keyword anywhere in this code. You never re-assign the global dicts, you only mutate them, so there is no need to declare them as global - Python finds them in the module scope anyway.
The problem though is that all module-level variables are per-process. If your receive function is always running in its own thread, it will never see any of the data from the view.

To fix this issue In Cloud Functions, you have no ability to ensure that there is a global variable in your code that's accessible by your functions. There are two things you need to know about how Cloud Functions works:
Under load, multiple server instances will be allocated to run your functions. These server instances don't share any state. Each of your functions is deployed to different server instances. Two functions will never run on the same server instance.
