With the rise of computation and data as pillars of science, institutions are struggling to provide large-scale training to their students and staff. Often, this leads to redundant, fragmented efforts, with each organization producing its own bespoke training material. In this talk, we report on a collaborative multi-tenant initiative to produce a shared corpus of interactive training resources in the Python language, designed as a digital common that can be adapted to diverse contexts and formats in French higher education and beyond.
