Introduction
Welcome to the comprehensive guide for building a simple yet effective Data Science Agent based on ReAct (Reasoning + Acting) Framework based on the CodeAct approach (see SmolAgents - that strongly inspired our approach - and the CodeAct paper)! This notebook shows how to create a open source agent that can perform data science tasks through iterative reasoning and code execution, powered by Together Code Interpreter (safe and scalable code excution).
The ReAct framework combines the power of large language models' reasoning capabilities with Python code execution, creating an agent that can:
- Think through problems step-by-step before taking action
- Execute Python code to perform data analysis, visualization, and machine learning modeling
- Observe results and adapt its approach based on outcomes
- Handle complex, multi-step data science workflows autonomously
The ReAct Data Science Workflow
The above ReAct Data Science Agent offers several key advantages:
- Iterative Problem Solving: The agent thinks through each step, executes code, observes results, and plans the next action
- Error Recovery: When code fails or produces unexpected results, the agent can analyze the error and try alternative approaches
- Adaptive Analysis: The agent can discover patterns in data and adjust its analysis strategy accordingly Code Generation: Generates and executes Python code for data manipulation, visualization, and machine learning
- Session Persistence: Maintains state across multiple code executions for complex workflows
Cookbook Contributions
- Set up a complete ReAct agent environment with configurable parameters
- Process complex data science tasks through iterative reasoning and execution
- Generate high-quality analysis results with proper visualizations and insights
- Handle real-world datasets and machine learning workflows
The modular design pattern we showcase makes each component transparent and customizable, allowing you to adapt the system to specific data science domains or analysis styles.
Whether you're a data scientist, researcher, or analyst, this cookbook provides the tools to transform your data science questions into comprehensive, executable analysis workflows.
Let's begin building our intelligent data science assistant! All the examples you see are built on top of Llama 3.3 70B!

Introduction to ReAct Framework
The ReAct (Reasoning + Acting) framework is a paradigm that combines reasoning and acting in large language models. Unlike traditional approaches that either only reason about problems or only take actions, ReAct interleaves these capabilities to create more effective problem-solving agents.
Core Principles of ReAct
- Reasoning: The agent reasons about what to do next, analyzing previous results and planning future actions
- Action: The agent executes code or uses tools to gather information or perform calculations
- Observation: The agent observes the results of actions and incorporates them into future reasoning
Why ReAct for Data Science?
Data science workflows are inherently iterative and exploratory. A data scientist typically:
- Examines data to understand its structure
- Tries different approaches based on initial findings
- Iterates on analysis based on intermediate results
- Adapts methodology when encountering unexpected patterns or errors
The ReAct framework naturally mirrors this human data science process, making it ideal for automated data analysis.
Agent Configuration Parameters
This section defines the key parameters that control the ReAct Data Science Agent behavior. These configuration settings allow you to customize the agent's operation according to your specific needs.
Key Configuration Areas:
- Model Selection: Defines which LLM to use for reasoning and code generation
- Execution Settings: Controls code execution environment and safety
- Iteration Limits: Sets boundaries on how many reasoning cycles to perform
- Output Configuration: Manages result formatting and display options
- Session Management: Configures persistent code execution session handling
Disclaimers ⚠️
This workflow involves multiple LLM calls and code execution, so please be mindful about resource management and costs.
Code Execution Safety: The agent executes Python code using Together Code Interpreter which offers a safe sandboxed environment to run code.
API Requirements: You will need a Together AI API key. Get it here.

Core Components
Code Execution Engine with Together Code Interpreter
The heart of our ReAct agent is the code execution capabilities powered with Together Code Interpreter (TCI) that safely runs Python code and processes results.
Why do we need TCI?
TCI helps the agent execute python code in a persistent and secure session without you having to build any local sandbox. This means that the engineering workload of building a safe python execution sandbox is offloaded to the online cloud offered by TCI.
Moreover, the fact that the session is persistent, means that the agent can use that to solve incremental data analysis tasks.
Even more important: we can upload files directly using TCI, which is perfect for datascience tasks!
Let's implement the main function:
[ ]
Quick Overview of Together Code Interpreter(TCI)
TCI allows us to run python code in the cloud and get results back. TCI will allocate a virtual machine for us where to run code and return any outputs. We will also get a session_id, that will allow us to re-use the current open session. TCI also comes with important data science libraries installed. For more details on TCI read the docs here.
[ ]
Session ID: ses_CPXBNGQfvtoiAv2WYy6zo
Status: completed
Outputs: [{'type': 'stdout', 'data': '4\n'}]
[ ]
{'session_id': 'ses_CPXBNGQfvtoiAv2WYy6zo',
, 'status': 'completed',
, 'outputs': [{'type': 'stdout', 'data': '16\n'}]} Utilities
We define a few utilities here. These are mainly functions for nicer printing and for file management.
File Management
This will later enable the agent to have access to uploaded files located in the data repository for workflows that require custom uploaded data.
[ ]
Output Processing and Display
These functions handle the formatting and display of execution results, including plots and data visualizations.
[ ]
Pretty Printing and Formatting
These functions create beautiful, readable output boxes for the agent's thoughts and results.
[ ]
Building the ReAct Agent
Now we'll construct the main ReAct agent class that orchestrates the reasoning and acting cycle.
The DataScientist ReAct Loop in Brief
Our DataScientist operates through a ReAct loop: It receives user input, makes a call to the Large Language Model (LLM), and receives a response. The LLM response is expected to be in one of two formats:
-
- a thought and action input (Python code), or
-
- a final answer summarizing the findings.
Our agent parse the thought and action input from the LLM response using a simple string matching. If the response is not in the expected format, it handles the error and continues. If python code is found it is then executed, and the results are displayed and added to the conversation history.
The ReAct loop continues until the task is complete or a maximum number of iterations is reached, allowing our agent to iteratively refine its analysis.

║ To begin, I will load the iris dataset, which is a classic multivariate dataset ║

║ petal length, and petal width. My goal is to create a scatter plot of sepal ║
║ length vs sepal width, where the points are colored according to their species. ║
║ This visualization will help me understand the relationship between sepal length ║

╠══════════════════════════════════════════════════════════════════════════════════╣
║ The summary statistics for each feature have been calculated and displayed. ║
║ These statistics provide a concise overview of the distribution of values for ║

║ The iris dataset contains 150 samples from three species of iris flowers, with 4 ║
║ features: sepal length, sepal width, petal length, and petal width. The dataset ║
║ is well-structured and contains no missing values. The summary statistics show ║
║ that the features have different means, standard deviations, and ranges. The ║
║ correlation matrix reveals strong positive correlations between sepal length and ║
║ petal length, and between petal length and petal width. The dataset can be used ║
║ for classification tasks, such as predicting the species of an iris flower based ║
║ on its features. Overall, the iris dataset is a classic and well-studied dataset ║

Key observations from the above task:
- The agent automatically imports necessary libraries
- It explores the data structure before creating visualizations
- Error handling if the dataset isn't immediately available
- Proper use of color coding for categorical variables

║ 'Parch', 'Pclass', 'Embarked', and '2urvived', along with several columns named ║

-------------------------------------------------------------------------------- ╔══════════════════════════════════════════════════════════════════════════════════╗ ║ 🎯 Final Answer ║ ╠══════════════════════════════════════════════════════════════════════════════════╣ ║ The analysis of the dataset revealed several key findings. Firstly, the ║ ║ '2urvived' column is strongly correlated with the 'Sex' column, indicating that ║ ║ females were more likely to survive than males. Secondly, the '2urvived' column ║ ║ is also correlated with the 'Fare' column, suggesting that passengers who paid ║ ║ higher fares were more likely to survive. The distribution of the '2urvived' ║ ║ column shows that there were 967 passengers who did not survive and 342 ║ ║ passengers who survived. The relationships between the '2urvived' column and the ║ ║ 'Sex' and 'Fare' columns were visualized using bar charts and histograms, ║ ║ confirming the findings from the correlation matrix. Overall, the analysis ║ ║ provides insights into the factors that influenced the survival of passengers, ║ ║ and can inform strategies for improving survival rates in similar situations. ║ ╚══════════════════════════════════════════════════════════════════════════════════╝

⚠️ Limitations
Our ReAct Data Science Agent operates within several important constraints that users should understand. The agent's analytical capabilities are bounded by the underlying language model's knowledge and reasoning abilities, meaning it may struggle with cutting-edge methods or miss domain-specific nuances without explicit context.
The agent can confidently apply statistical tests without properly validating assumptions, potentially leading to methodologically flawed analyses. It also has blind spots around data quality assessment and cannot intuitively recognize sampling biases or other subtle issues that experienced analysts would catch.
From an ethical standpoint, the agent may perpetuate algorithmic biases or suggest analyses that inadvertently violate privacy regulations without explicit guidance.
