modernize-scientific-stack

Guidance for modernizing legacy Python 2 scientific computing code to Python 3. This skill should be used when tasks involve converting outdated scientific Python scripts (using deprecated libraries like ConfigParser, cPickle, urllib2, or Python 2 syntax) to modern Python 3 equivalents with contemporary scientific stack (NumPy, pandas, scipy, matplotlib). Applies to data processing, analysis pipelines, and scientific computation modernization tasks.
