Python code for calculating the resilience and the prospective resilience in networks. This code accompanies the recent paper:

Resilience and evolvability of protein-protein interaction networks. by Brennan Klein, Ludvig Holmér, Keith M. Smith, Mackenzie M. Johnson, Anshuman Swain, Laura Stolp, Ashley I. Teufel, and April S. Kleppe. (2020).

This code is written in Python 3.x and uses the following packages:

• NetworkX
• Scipy
• Numpy
• And for replicating figures, you will need:
  • matplotlib
  • Pandas
