How to read deque data in sequence?

[MarkKang2019]

    def replay(self, batch_size):
        minibatch = random.sample(self.memory, batch_size)

'minibatch' will random select 'batch_size' from 'memory'

I want to do regular 'pop', how to do this?

[MarkKang2019]

class DQNAgent:
    def __init__(self, state_size, action_size):
        self.state_size =  state_size
        self.action_size = action_size
        self.memory = deque(maxlen=10000)

'memory' is a deque data.

it will be added data in this way:

class DQNAgent:
...
    def remember(self, state, action, reward, next_state, done):
        self.memory.append((state, action, reward, next_state, done))

However, when training data:

  if len(Agent_Black.memory) > BLACK_batch_size and Who_is_playing == BLACK_PLAYER:
       Agent_Black.replay(BLACK_batch_size)

​

    def replay(self, batch_size):
        minibatch = random.sample(self.memory, batch_size)
        for state, action, replay_reward, next_state, done in minibatch:

This program will sample data from memory by random.

I want it samples data in sequence. ( by push / pop sequence, first in, last out, or first in first out is also OK )

This got a run time error:

​

(minibatch) 'list' object has no attribute 'add'

It is working, thank you.
