PandasAI is a Python library that adds Generative AI capabilities to pandas, the popular data analysis and manipulation tool. It is designed to be used in conjunction with pandas, and is not a replacement for it.

Disclaimer: GDP data was collected from this source, published by World Development Indicators - World Bank (2022.05.26) and collected at National accounts data - World Bank / OECD. It relates to the year of 2020. Happiness indexes were extracted from the World Happiness Report. Another useful link.
PandasAI is designed to be used in conjunction with pandas. It makes pandas conversational, allowing you to ask questions to your data in natural language.
For example, you can ask PandasAI to find all the rows in a DataFrame where the value of a column is greater than 5, and it will return a DataFrame containing only those rows:
import pandas as pd
from pandasai import SmartDataframe
# Sample DataFrame
df = pd.DataFrame({
"country": ["United States", "United Kingdom", "France", "Germany", "Italy", "Spain", "Canada", "Australia", "Japan", "China"],
"gdp": [19294482071552, 2891615567872, 2411255037952, 3435817336832, 1745433788416, 1181205135360, 1607402389504, 1490967855104, 4380756541440, 14631844184064],
"happiness_index": [6.94, 7.16, 6.66, 7.07, 6.38, 6.4, 7.23, 7.22, 5.87, 5.12]
})
# Instantiate a LLM
from pandasai.llm import OpenAI
llm = OpenAI(api_token="YOUR_API_TOKEN")
df = SmartDataframe(df, config={"llm": llm})
df.chat('Which are the 5 happiest countries?')The above code will return the following:
6 Canada
7 Australia
1 United Kingdom
3 Germany
0 United States
Name: country, dtype: object
Of course, you can also ask PandasAI to perform more complex queries. For example, you can ask PandasAI to find the sum of the GDPs of the 2 unhappiest countries:
df.chat('What is the sum of the GDPs of the 2 unhappiest countries?')The above code will return the following:
19012600725504
You can also ask PandasAI to draw a graph:
df.chat(
"Plot the histogram of countries showing for each the gdp, using different colors for each bar",
)
You can save any charts generated by PandasAI by setting the save_charts parameter to True in the PandasAI constructor. For example, PandasAI(llm, save_charts=True). Charts are saved in ./pandasai/exports/charts .
Additionally, you can also pass in multiple dataframes to PandasAI and ask questions relating them.
import pandas as pd
from pandasai import SmartDatalake
from pandasai.llm import OpenAI
employees_data = {
'EmployeeID': [1, 2, 3, 4, 5],
'Name': ['John', 'Emma', 'Liam', 'Olivia', 'William'],
'Department': ['HR', 'Sales', 'IT', 'Marketing', 'Finance']
}
salaries_data = {
'EmployeeID': [1, 2, 3, 4, 5],
'Salary': [5000, 6000, 4500, 7000, 5500]
}
employees_df = pd.DataFrame(employees_data)
salaries_df = pd.DataFrame(salaries_data)
llm = OpenAI()
dl = SmartDatalake([employees_df, salaries_df], config={"llm": llm})
dl.chat("Who gets paid the most?")The above code will return the following:
Oh, Olivia gets paid the most.
You can find more examples in the examples directory.
PandasAI also provides a number of shortcuts (beta) to make it easier to ask questions to your data. For example, you can ask PandasAI to clean_data, impute_missing_values, generate_features, plot_histogram, and many many more.
# Clean data
df.clean_data()
# Impute missing values
df.impute_missing_values()
# Generate features
df.generate_features()
# Plot histogram
df.plot_histogram(column="gdp")Learn more about the shortcuts here.
In order to generate the Python code to run, we take the dataframe head, we randomize it (using random generation for sensitive data and shuffling for non-sensitive data) and send just the head.
Also, if you want to enforce further your privacy you can instantiate PandasAI with enforce_privacy = True which will not send the head (but just column names) to the LLM.
