2. Our Agenda
What is Data Science?
Introduction to Python
Python Tools for Data Science
A bit of Python for Big Data Processing
Questions

3. Data Science

4. Data Scientist asks relevant
real world questions

And hopefully,
discovers
actionable
recommendations
from data

5. TOOLS

6. WHAT IS
PYTHON?
“THE NAME PYTHON COMES
FROM THE SURREAL BRITISH
COMEDY GROUP MONTY PYTHON,
NOT FROM THE SNAKE. PYTHON
PROGRAMMERS ARE
AFFECTIONATELY CALLED
PYTHONISTAS, AND BOTH MONTY
PYTHON AND SERPENTINE
REFERENCES USUALLY PEPPER
PYTHON TUTORIALS AND
DOCUMENTATION.”
