How can I share a (global) variable between different custom python modules.

[piyush kirtivardhan]

code sample:
# Define the global dictionary
global_dict = {}

def update_global_dict(key, value):
    """
    Update the global dictionary with the given key-value pair.
    """
    global global_dict
    global_dict[key] = value
    print(f"Updated global_dict: {global_dict}")

def fetch_from_global_dict(key):
    """
    Fetch the value from the global dictionary for the given key.
    """
    global global_dict
    return global_dict.get(key, "Key not found")
----------------------------------------------------------------------------------------
I am using the below way to achieve it.

def update_global_dict(key, value):
    __salt__['data.update'](key, pickle.dumps(value))


def fetch_from_global_dict(key):
    status = __salt__['data.has_key'](key)
    return pickle.loads(status)

but there are some issue in performance:
when i am try to access it multiple time:
it throwing error in deserialization and serialization error.

is there any way to so we can achieve the values in global variable so i don't have any problem in  fetch and storing the data in custom python modules?
Saving in file and opening and reading file again is not an option.
