Why Python? The SQL Analyst's Next Step

The Limit of SQL

I was a SQL wizard. I could write 500-line CTEs and recursive queries. But one day, the data science team asked: *"Can you run a quick regression on this dataset?"*

I froze. SQL can aggregate, filter, and join—but it can't build predictive models. That day, I started learning Python.

Why Python?

1. **Machine Learning**: Scikit-learn, TensorFlow, PyTorch.

2. **Data Manipulation**: Pandas (which we'll learn soon).

3. **Visualization**: Matplotlib, Seaborn, Plotly.

4. **Flexibility**: Python can do anything—web scraping, APIs, automation.

The Path

Days 101-150 will take you from "I've never written Python" to "I can build a predictive model from scratch."

Your First Task

Install Python (Anaconda recommended). Open a Jupyter Notebook and run:

print("Hello, Data Science!")
