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
- Steps in building a model.
- Supervised and unsupervised algorithms.
- The choice between regression and classification.
Hands-on work
Integration of Python scripts in the installed environment, for analysis.
4 Model evaluation procedures
- Re-sampling techniques in training, validation and test games.
- Testing the representativeness of training data.
- Performance measurements for predictive models.
- Confusion and cost matrix, ROC and AUC curves.
Hands-on work
Set up dataset sampling. Perform evaluation tests on several supplied models.

Hands-on work
Implement regressions and classifications on several types of data.
6 Unsupervised algorithms
- Hierarchical clustering.
- Non-hierarchical clustering.
- Mixed approaches.
Hands-on work
Unsupervised clustering on multiple datasets.

I had misjudged the content of the training offered by my employer following my request to progress in Python. According to the title, I was expecting more of a Data Analyst than a Data Scientist, using Python to load and transform data (ETL). I probably wouldn't be able to use the statistics part, but it was very interesting, and it seems to me that it would be possible to put together an 'operational' package for this ETL part in 3 days.
