This solution defines a function `solution` that uses the agent's methods to interact with the environment and complete the task of putting a pencil on a shelf. The function goes through steps to find a pencil in one of the receptacles and then put it on a shelf. Each step is marked with a comment, and assertions are used to check if the steps are successful. Finally, the `solution` function is called to solve the task.

Given a list of receptacles, please sort them in descending order based on the likelihood of finding a pencil in each of them. The list of receptacles is: ['bed 1', 'desk 2', 'desk 1', 'drawer 6', 'drawer 5', 'drawer 4', 'drawer 3', 'drawer 2', 'drawer 1', 'garbagecan 1', 'laundryhamper 1', 'safe 1', 'shelf 6', 'shelf 5', 'shelf 4', 'shelf 3', 'shelf 2', 'shelf 1']. You should directly return a Python list.

Prompt: 
Given a list of receptacles, please sort them in descending order based on the likelihood of finding a pencil in each of them. The list of receptacles is: ['bed 1', 'desk 2', 'desk 1', 'drawer 6', 'drawer 5', 'drawer 4', 'drawer 3', 'drawer 2', 'drawer 1', 'garbagecan 1', 'laundryhamper 1', 'safe 1', 'shelf 6', 'shelf 5', 'shelf 4', 'shelf 3', 'shelf 2', 'shelf 1']. You should directly return a Python list.

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

Prompt: 
From the observation, get the identifier of an object. For example, On the cabinet 1, you see a cloth 2, and a pencil 1. The identifier of cloth is 2. Now, On the desk 2, you see a alarmclock 3, a bowl 3, a creditcard 2, a mug 1, and a pencil 2. The identifier of the pencil? Only Output a single number without any other words.

```

This solution defines the steps needed to put a vase in the safe by interacting with the household environment using the agent's methods. It follows a similar structure to the example solution provided earlier for putting a soapbar on the countertop. The solution uses the assistant's help to identify the receptacles where a vase is likely to appear, find the vase, take it, and finally put it in the safe.

From the observation, get the identifier of an object. For example, On the cabinet 1, you see a cloth 2, and a saltshaker 1. The identifier of cloth is 2. Now, On the countertop 3, you see a cellphone 3, a cellphone 2, a fork 3, a glassbottle 2, a houseplant 1, a knife 2, a lettuce 1, a saltshaker 1, a statue 1, a vase 2, and a vase 1.

Prompt: 
Given a list of receptacles, please sort them in descending order based on the likelihood of finding a mug in each of them. The list of receptacles is: ['bed 1', 'desk 2', 'desk 1', 'drawer 6', 'drawer 5', 'drawer 4', 'drawer 3', 'drawer 2', 'drawer 1', 'garbagecan 1', 'laundryhamper 1', 'safe 1', 'shelf 6', 'shelf 5', 'shelf 4', 'shelf 3', 'shelf 2', 'shelf 1']. You should directly return a Python list.
Response: 
['shelf 6', 'shelf 5', 'shelf 4', 'shelf 3', 'shelf 2', 'shelf 1', 'desk 2', 'desk 1', 'drawer 6', 'drawer 5', 'drawer 4', 'drawer 3', 'drawer 2', 'drawer 1', 'bed 1', 'garbagecan 1', 'laundryhamper 1', 'safe 1']

This code defines a solution function that uses the agent's methods to interact with the environment and complete the task of putting a mug in a desk. The function goes through steps of finding a receptacle with a mug, taking the mug, and putting it in the desk. Assertions are used to check the success of each step. Finally, the solution function is called with the agent to solve the task.

Prompt: 
Given a list of receptacles, please sort them in descending order based on the likelihood of finding a soapbottle in each of them. The list of receptacles is: ['cabinet 4', 'cabinet 3', 'cabinet 2', 'cabinet 1', 'countertop 1', 'garbagecan 1', 'handtowelholder 2', 'handtowelholder 1', 'sinkbasin 2', 'sinkbasin 1', 'toilet 1', 'toiletpaperhanger 1', 'towelholder 1']. You should directly return a Python list.
Response: 
['sinkbasin 1', 'sinkbasin 2', 'handtowelholder 1', 'handtowelholder 2', 'cabinet 1', 'cabinet 2', 'cabinet 3', 'cabinet 4', 'toilet 1', 'countertop 1', 'toiletpaperhanger 1', 'towelholder 1', 'garbagecan 1']
====================

Prompt: 
From the observation, get the identifier of an object. For example, On the cabinet 1, you see a cloth 2, and a soapbottle 1. The identifier of the soapbottle is 1. Now, On the countertop 1, you see a soapbottle 1, and a spraybottle 2. The identifier of the soapbottle? Only Output a single number without any other words.

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

Prompt: 
Given a list of receptacles, please sort them in descending order based on the likelihood of finding a peppershaker in each of them. The list of receptacles is: ['cabinet 6', 'cabinet 5', 'cabinet 4', 'cabinet 3', 'cabinet 2', 'cabinet 1', 'coffeemachine 1', 'countertop 3', 'countertop 2', 'countertop 1', 'drawer 3', 'drawer 2', 'drawer 1', 'fridge 1', 'garbagecan 1', 'microwave 1', 'shelf 3', 'shelf 2', 'shelf 1', 'sinkbasin 1', 'stoveburner 4', 'stoveburner 3', 'stoveburner 2', 'stoveburner 1', 'toaster 1']. You should directly return a Python list.
Response: 
['fridge 1', 'cabinet 1', 'cabinet 2', 'cabinet 3', 'cabinet 4', 'cabinet 5', 'cabinet 6', 'countertop 1', 'countertop 2', 'countertop 3', 'drawer 1', 'drawer 2', 'drawer 3', 'shelf 1', 'shelf 2', 'shelf 3', 'stoveburner 1', 'stoveburner 2', 'stoveburner 3', 'stoveburner 4', 'coffeemachine 1', 'garbagecan 1', 'microwave 1', 'sinkbasin 1', 'toaster 1']
====================

Prompt: 
From the observation, get the identifier of an object. For example, On the cabinet 1, you see a cloth 2, and a peppershaker 1. The identifier of peppershaker is 1. Now, On the countertop 3, you see a apple 1, a bread 1, a butterknife 2, a butterknife 1, a cup 2, a egg 2, a houseplant 1, a knife 3, a knife 2, a pan 2, a peppershaker 1, and a vase 3. The identifier of the peppershaker? Only Output a single number without any other words.

['safe 1', 'drawer 5', 'drawer 4', 'drawer 3', 'drawer 2', 'drawer 1', 'cabinet 4', 'cabinet 3', 'cabinet 2', 'cabinet 1', 'dresser 1', 'shelf 12', 'shelf 11', 'shelf 10', 'shelf 9', 'shelf 8', 'shelf 7', 'shelf 6', 'shelf 5', 'shelf 4', 'shelf 3', 'shelf 2', 'shelf 1', 'sidetable 1', 'armchair 1', 'sofa 1', 'garbagecan 1']
====================

Prompt: 
From the observation, get the identifier of an object. For example, On the cabinet 1, you see a watch 2 and a book 1. The identifier of the watch is 2. Now, On the dresser 1, you see a laptop 1, a remotecontrol 1, a tissuebox 1, a vase 3, a vase 2, and a watch 1. The identifier of the watch? Only Output a single number without any other words.

This code defines a solution function that interacts with the household environment to complete the task of putting a peppershaker on a drawer. The function follows a general plan of finding the receptacles where a peppershaker is likely to appear, going to each receptacle to find the peppershaker, taking the peppershaker, and finally putting it on a drawer. The function includes steps with assertions to ensure the success of each action taken by the agent.
