Python is a popular programming language for data science. The document discusses how Python and its tools like Pandas, Scikit-learn, and MLflow can be used for data analysis, machine learning, and big data processing. It also provides an overview of data science concepts and the Python tools and libraries commonly used by data scientists in their work.

- 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 Source: Python Data Analytics
- 4. Data Scientist asks relevant real world questions Source: http://drewconway.com/zia/2013/3/26/the-data-science-venn-diagram And hopefully, discovers actionable recommendations from data

- 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.” Automate the Boring Stuff with Python
