1. How do I create a global variable that can be accessed by all classes?

2. I am using `dogpile.cache` to store data in the cache [1], but if I set and get the same key from different modules, I don't get the value. Here is an example in [2]. The value than I get is `NO_VALUE.NO_VALUE`. Why this happens?

setter is the setter.py
getter is the getter.py
Memoize is the file in [1].


[1] my dogpile class `Memoize.py`

    from dogpile.cache import make_region

    region = make_region().configure('dogpile.cache.memory')

    def save(key, value):
      """
      general purpose method to save data (value) in the cache
    
      :param key (string) key of the value to be saved in cache
      :param value (any type) the value to be saved
      """
      region.set(key, value)


    def get(key):
      """
      general purpose method to get data from the cache
 
      :param key (string) key of the data to be fetched
      :return value (any type) data to be returned from the cache
      """
      return region.get(key)


[2] My python example

`setter.py`

    def myset(value):     
      Memoize.save("myvalue", value)

`getter.py`

   def myget():
      return Memoize.get("myvalue") <- this value is NO_VALUE. NO_VALUE

My class:

    setter.myset(123)
    getter.myget()
