NetPy '19: Introduction to Network Analysis in Python

Workshop instructor

Asst. Prof. Lovro Šubelj, PhD, University of Ljubljana

Workshop schedule

Tuesday, 10th December 2019 at 3:30 PM (4 hours with breaks)

Workshop location

Lecture room 3 at UL FRI, Večna pot 113, Ljubljana, Slovenia

Materials and forum
High-level description

The workshop is primarily aimed at Python programmers, either academics, professionals or students, that wish to learn the basics of modern network science and practical analyses of complex real networks, such as social, information and biological networks. Familiarity with the basics of probability theory, statistics and linear algebra is strongly encouraged. The workshop is based on masters level course Network Analysis offered at University of Ljubljana, Faculty of Computer and Information Science.

Recommended prerequisites

It is recommended that attendees bring a laptop with working installation of Python, NetworkX and CDlib packages, and necessary dependencies. Alternatively, you can work with any other network analysis package such as igraph, graph-tool or Finally, for the purposes of visualization of smaller networks, it is recommended to have working installation of some network analysis software such as Gephi or visone.
