In the age of AI, many of our tasks have been automated especially after the launch of ChatGPT. One such tool that uses the power of ChatGPT to ease data manipulation task in Python is PandasAI. It leverages the power of ChatGPT to generate Python code and executes it. The output of the generated code is returned. Pandas AI helps performing tasks involving pandas library without explicitly writing lines of code. In this article we will discuss about how one can use Pandas AI to simplify data manipulation.

What is Pandas AI

Using generative AI models from OpenAI, Pandas AI is a pandas library addition. With simply a text prompt, you can produce insights from your dataframe. It utilises the OpenAI-developed text-to-query generative AI. The preparation of the data for analysis is a labor-intensive process for data scientists and analysts. Now they can carry on with their data analysis. Data experts may now leverage many of the methods and techniques they have studied to cut down on the time needed for data preparation thanks to Pandas AI. PandasAI should be used in conjunction with Pandas, not as a substitute for Pandas. Instead of having to manually traverse the dataset and react to inquiries about it, you can ask PandasAI these questions, and it will provide you answers in the form of Pandas DataFrames. Pandas AI wants to make it possible for you to visually communicate with a machine that will then deliver the desired results rather than having to program the work yourself. To do this, it uses the OpenAI GPT API to generate the code using Pandas library in Python and run this code in the background. The results are then returned which can be saved inside a variable.

How Can I use Pandas AI in my projects

1. Install and Import of Pandas AI library in python environment

Execute the following command in your jupyter notebook to install pandasai library in python

!pip install -q pandasai

Import pandasai library in python

Python3

import pandas as pd
import numpy as np
from pandasai import PandasAI
from pandasai.llm.openai import OpenAI

                    

2. Add data to an empty DataFrame

Make a dataframe using a dictionary with dummy data

Python3

data_dict = {
    "country": [
        "Delhi",
        "Mumbai",
        "Kolkata",
        "Chennai",
        "Jaipur",
        "Lucknow",
        "Pune",
        "Bengaluru",
        "Amritsar",
        "Agra",
        "Kola",
    ],
    "annual tax collected": [
        19294482072,
        28916155672,
        24112550372,

Pros and Cons of Pandas AI

Pros of Pandas AI

  • Can easily perform simple tasks without having to remember any complex syntax
  • Capable of giving conversational replies
  • Easy report generation for quick analysis or data manipulation

Cons of Pandas AI

  • Cannot perform complex tasks
  • Cannot create or interact with variables other than the passed dataframe

Frequently Asked Questions (FAQs)

1. Is Pandas AI replacing Pandas ?

No, Pandas AI is not meant to replace Pandas. Though Pandas AI can easily perform simple tasks, it still faces difficulty performing some complex tasks like saving the dataframe, making a correlation matrix and many more. Pandas AI is best for quick analysis, data cleaning and data manipulation but when we have to perform some complex functions like join, save dataframe, read a file, or create a correlation matrix we should prefer Pandas. Pandas AI is just an extension of Pandas, for now it cannot replace Pandas.

2. When to use Pandas AI ?

For simple tasks one could consider using Pandas AI, here you won’t have to remember any syntax. All you have to do is design a very descriptive prompt and rest will be done by Open AI’s LLM. But if you want to perform some complex tasks, you should prefer using Pandas.

3. How does Pandas AI work in the backend?

Pandas AI takes in the dataframe and your query as input and passes it to a collection of OpenAI’s LLM’s. Pandas AI uses ChatGPT’s API in the backend to generate the code and executes it. The output after execution is returned to you.

4. Can PandasAI work without OpenAI’s API?

Yes, other than ChatGPT you can also use Google’s PaLm model, Open Assistant LLM and StarCoder LLM for code generation.

5. Which to use Pandas or PandasAI for Exploratory Data Analysis?

You can first try using PandasAI to check if the data is good to perform an in depth analysis, then you can perform an in-depth analysis using Pandas and other libraries.

6. Can PandasAI use numpy attributes or functions?

No, it does not have the ability to use numpy functions. All computations are performed either by using Pandas or in-built python functions in the backend.

Conclusion

In this article we focused on how to use PandasAI to perform all the major functionality supported by Pandas to perform a quick analysis on your dataset. By automating several operations, it without a doubt boosts productivity. It’s important to keep in mind that even though PandasAI is a powerful tool, the Pandas library must still be used. PandasAI is therefore a beneficial addition that improves the capability of the pandas library and further increases the effectiveness and simplicity of dealing with data in Python.
