Prerequisites
Mastery of Python programming. Basic knowledge of statistics or completion of the course "Statistics, mastering the fundamentals" (Ref. STA).
Practical details
Developing/performing analyses with Python, using Pandas, Numpy and SciPy modules.
Course schedule
1 Introduction to the scientific Python ecosystem
- Overview of Python's scientific ecosystem: must-have libraries.
- Know where to find new bookstores and assess their sustainability.
- The main open source tools and software for data science.
Hands-on work
Installation of Python 3, Anaconda and Jupiter Notebook.
2 Working with data in Python
- Python's scientific foundation: the SciPy Stack.
- Best practices for getting your data science project off to a good start with Python.
- Scientific file formats and libraries for manipulating them.
- Pandas: analysis of tabular data (CSV files, Excel, etc.), statistics, pivots, filters, searches, etc.
- NumPy: numerical calculation and linear algebra (vectors, matrices, images).
- Data extraction, preparation, cleaning.
Hands-on work
Write Python scripts to work with data from files, to apply filters, formatting and cleaning processes.
3 Introduction to modeling

I thought this course was aimed at people who already had some experience with Python and would therefore move on quite quickly to using advanced data analysis techniques. In the end, we started with the basics of Python and worked our way up to a practical example of data science. So we didn’t go as far as I would have liked.
