This article makes things complicated.
Forget about the box metaphore in it.

Variablea are copied to functions by address.
Inside a function, while some operations (like .append()) are applied through dereferencing ,
others like reassignment are done by assigning a new address.

https://stackoverflow.com/questions/24815771/python-inverse-function-of-id-built-in-function

================================

Is there a reverse or inverse of the id built-in function? 
I was thinking of using it to encode and decode string without taking too much time or having a lot of overhead like the PyCrypto library. 
The need for me is quite simple so I don't want to use PyCrypto for a simple encode and decode.

Something like:

def ran_check1(num, low, high):
    return int(num in range(low, high))

def ran_check2(num,low,high):
    if num in range(low,high):
        print('{num} is not in the range of {low} and {high}')
    else:
        print('{num} is not in the range of {low} and {high}')
        
ran_check1(1,2,3)

I would like my laptop to hibernate itself when the battery level is 10% to be sure it has enough power to complete the operation properly. Actually if I don't pay attention my laptop informs me it will hibernate when it's too late, so instead it brutally shuts down. This kills lithium batteries and is not acceptable.



    Start dconf-editor
    Browse to org -> gnome -> settings-daemon -> plugins -> power
    Change the values of percentage-critical and percentage-action to the level you require
