title: "Custom Response"
---

PandasAI offers the flexibility to handle chat responses in a customized manner. By default, PandasAI includes a ResponseParser class that can be extended to modify the response output according to your needs.

You have the option to provide a custom parser, such as `StreamlitResponse`, to the configuration object like this:

## Example Usage

```python

import os
import pandas as pd
from pandasai import SmartDatalake
from pandasai.responses.response_parser import ResponseParser

# This class overrides default behaviour how dataframe is returned
# By Default PandasAI returns the SmartDataFrame
class PandasDataFrame(ResponseParser):

    def __init__(self, context) -> None:
        super().__init__(context)

    def format_dataframe(self, result):
        # Returns Pandas Dataframe instead of SmartDataFrame
        return result["value"]


employees_df = pd.DataFrame(
    {
        "EmployeeID": [1, 2, 3, 4, 5],
        "Name": ["John", "Emma", "Liam", "Olivia", "William"],
        "Department": ["HR", "Sales", "IT", "Marketing", "Finance"],
    }
)

salaries_df = pd.DataFrame(
    {
        "EmployeeID": [1, 2, 3, 4, 5],
        "Salary": [5000, 6000, 4500, 7000, 5500],
    }
)

# By default, unless you choose a different LLM, it will use BambooLLM.
# You can get your free API key signing up at https://pandabi.ai (you can also configure it in your .env file)
os.environ["PANDASAI_API_KEY"] = "YOUR_API_KEY"

agent = SmartDatalake(
    [employees_df, salaries_df],
    config={"llm": llm, "verbose": True, "response_parser": PandasDataFrame},
)

response = agent.chat("Return a dataframe of name against salaries")
# Returns the response as Pandas DataFrame

```

## Streamlit Example

```python

import os
import pandas as pd
from pandasai import SmartDatalake
from pandasai.responses.streamlit_response import StreamlitResponse

employees_df = pd.DataFrame(
    {
        "EmployeeID": [1, 2, 3, 4, 5],
        "Name": ["John", "Emma", "Liam", "Olivia", "William"],
        "Department": ["HR", "Sales", "IT", "Marketing", "Finance"],
    }
)

salaries_df = pd.DataFrame(
    {
        "EmployeeID": [1, 2, 3, 4, 5],
        "Salary": [5000, 6000, 4500, 7000, 5500],
    }
)


# By default, unless you choose a different LLM, it will use BambooLLM.
# You can get your free API key signing up at https://pandabi.ai (you can also configure it in your .env file)
os.environ["PANDASAI_API_KEY"] = "YOUR_API_KEY"

agent = SmartDatalake(
    [employees_df, salaries_df],
    config={"verbose": True, "response_parser": StreamlitResponse},
)

agent.chat("Plot salaries against name")
```
