BIG NEWS: #ChatGPT breaks #Python vs #R Barriers in Data Science!

Data science teams everywhere rejoice.

A mind-blowing thread (with a FULL chatgpt prompt walkthrough). 🧵

#datascience #rstats
It's NOT R VS Python ANYMORE!

This is 1 example of how ChatGPT can speed up data science & GET R & PYTHON people working together.

(it blew my mind)
This example combines #R, #Python, and #Docker.

I created this example in under 10 minutes from start to finish.
I’m an R guy.

And I prefer doing my business research & analysis in R.

It's awesome. It has:

1. Tidyverse - data wrangling + visualization
2. Tidymodels - Machine Learning
3. Shiny - Apps
But the rest of my team prefers Python.

And they don't like R... it's just weird to them.

So I wanted to see if I could show them how we could work together...
Let’s start with a prompt.

I asked chatgpt to find a data set that I used for this example. Image
...ChatGPT found it... Image
... And gave me this code to read the data... Image
I prefer the tidyverse, so I asked Chatgpt to update the code. Image
That looks better. Image
With the data in hand, it’s time for some Data Science.

I asked this simple question. Image
ChatGPT's response was impressive. Image
But, even though I’m an R guy, my team uses Python for Deployment…

In the past, that’s a huge problem.

(resulting in days of translations from R to Python with Google and StackOverflow)
But now, that’s 1 minute of effort with chatGPT.

Can I show you?
I asked chatgpt to convert the R script to python... Image
And in 10 seconds chatgpt made this python code with pandas and scikit learn. Image
ChatGPT did in 10 seconds something that would have taken me 2 hours.

But let’s continue.

The reason we had to convert to Python is for “deployment”

Deployment is just a fancy word for allowing others to access my model so they can use it on-demand.
So I asked chatGPT this: Image
And ChatGPT made me a Python API using FastAPI. Image
But this code is useless…

… Without a docker environment.

So I asked chatGPT to make one: Image
And chatGPT delivered my Docker Environment's Dockerfile: Image
So in under 10 minutes, I had ChatGPT:

1. Make my research script in R.

2. Create my production script in Python for my Team

3. And create the API + Docker File to deploy it.
But when I showed my Python team, instead of excited...

...They were worried.

And I said, "Listen. There's nothing to be afraid of."

"ChatGPT is a productivity enhancer."

They didn't believe me.
My Conclusion:

You have a choice. You can rule AI.

Or, you can let AI rule you.

What do you think the better choice is?
If you want help, I'd like you to join me on a free #ChatGPT for #DataScientists Workshop on April 26th. And I will help you Rule AI.

What's the next step?

Understanding probability is essential in data science.

In 4 minutes, I'll demolish your confusion.

Let's go! Image
1. Statistical Distributions:

There are 100s of distributions to choose from when modeling data. Choices seem endless. Use this as a guide to simplify the choice. Image
2. Discrete Distributions:

Discrete distributions are used when the data can take on only specific, distinct values. These values are often integers, like the number of sales calls made or the number of customers that converted.

RIP manual research workflows.

Someone just open-sourced what comes after Karpathy’s AutoResearch.

It’s called AutoResearchClaw.

And this thing is insane. Image
A few weeks ago, Karpathy showed where research was heading:

AI agents running the experiment loop.

That was already a big signal.

AutoResearchClaw takes it even further.

It doesn’t just help with research.

It tries to automate the entire scientific method end-to-end.
You give it a raw idea.

One CLI command.

Then it runs.

Not just “brainstorming.”

Not just “summarizing.”

Actually running the workflow.

These 7 statistical analysis concepts have helped me as an AI Data Scientist.

Let's go: 🧵 Image
Step 1: Learn These Descriptive Statistics

Mean, median, mode, variance, standard deviation. Used to summarize data and spot variability. These are key for any data scientist to understand what’s in front of them in their data sets. Image
2. Learn Probability

Know your distributions (Normal, Binomial) & Bayes’ Theorem. The backbone of modeling and reasoning under uncertainty. Central Limit Theorem is a must too. Image

2. Supported Documents

MarkItDown supports:

- PDF
- PowerPoint
- Word
- Excel
- Images (EXIF metadata and OCR)
- Audio (EXIF metadata and speech transcription)
- HTML
- Text-based formats (CSV, JSON, XML)

RIP document extractors.

Google just released LangExtract: Open-source. Free. Better than $100K enterprise tools.

Here’s what it does: 🧵 Image
What it does:

→ Extracts structured data from messy text
→ Grounds every field to the exact source location
→ Handles 100+ page docs
→ Generates interactive HTML for verification
→ Works with Gemini + local models Image
What it replaces:

→ Regex/fragile parsing
→ Custom NER pipelines
→ Expensive extraction APIs
→ Manual data entry Image

Data science killed itself.

Not because AI showed up. Because too much of the field confused running a model with understanding one. Image
For years, data science rewarded people for producing outputs:

A model score
A dashboard
A notebook
A prediction
A nice chart

And a lot of that work looked impressive.
But underneath it, there was a problem:

No understanding of the business value (or lack of) it generated.
