i'm testing on botframework emulator then session is always clear per question.
im not sure if problem is botframework , emulator or my code. what i want is if i save session name and value it must be kept. please check this issue. example result below (but value must be all same) i just used your Rich-Cards-Bot sample:

User_code: O6ZzukPijRcjY18w
User_code: 0E1nfH6m2tMuDRcW
User_code: erZyRVLMEiM2cS7I
User_code: 1lb4Kj5azHydF59K
User_code: PORfe9xn5M2beGuh
User_code: 9nZQxgocpJI32keb
User_code: GaCLP8FkyzgZOfp4
User_code: 0ykPMoFQzDC7rtap
User_code: p7EhxhMF4XFca7EL
User_code: Ys6V372dFuddG5Ol
User_code: LfIIMt05fMkldTE4

I'm not entirely sure what you are trying to accomplish by using sessions, but I came up with a solution using User State in the BotFramework that might work for you.

Right below where the memory is initialized in the main.py file, uncomment user_state = UserState(memory). It should be on line 32 in the Rich-Cards-Bot example, but it might be further down since I believe you've imported a few packages. You also need to uncomment ADAPTER.use(user_state) on line 35.

Then in the handle_message function, you can either access the User_code from the user_state or create a new User_code in the user_state if it doesn't exist. Your code should look something like this:

# Create MemoryStorage, UserState and ConversationState
memory = MemoryStorage()
user_state = UserState(memory)
...
# Register both State  middleware on the adapter.
ADAPTER.use(user_state)
ADAPTER.use(conversation_state)

...

async def handle_message(context: TurnContext) -> web.Response:
    # Access the state of the user
    user = await user_state.get(context)

    if not hasattr(user, 'User_code'):
        user.User_code = ''.join([random.choice(string.ascii_letters + string.digits) for _ in range(16)]) 
    
    print(user.User_code)

    ...

    return web.Response(status=202)

...

async def messages(req: web.web_request) -> web.Response:
    body = await req.json()
    activity = Activity().deserialize(body)
    auth_header = req.headers['Authorization'] if 'Authorization' in req.headers else ''
    try:
        return await ADAPTER.process_activity(activity, auth_header, request_handler)
    except Exception as e:
        raise e

app = web.Application()
app.router.add_post('/', messages)

try:
    web.run_app(app, host='localhost', port=PORT)
except Exception as e:
    raise e

Using the user state, the User_code stays consistent between messages, and the output looks like this:

User_code: BGjvg9FkUCJeUoOa
User_code: BGjvg9FkUCJeUoOa
User_code: BGjvg9FkUCJeUoOa

If this solution doesn't work for what you are trying to do, please let me know and I will look deeper into the issue you are having with sessions.

Thanks for your reply @tdurnford. simply this is what i want. so.... by using this, we could save user information right? and its for multi user that's all. Thanks alot! and i think this is what @varunreddycs asked for state data. if we have example code with this it will be better for the starter. if you don't mind i would like to ask one thing more that how can i use adaptive_card button data as an input? example i have a Card with button value yes or no. on javascript or c# botframework i could see their value can be in the chat text, or as input value. i'm waiting for you great answer :)

Yes, you can store user information such as name and id in the user state and the data will be preserved for each user between conversations.
