• Pure Python!
  • Jython (Python in Java) OK!
• AIDA (Abstract Interfaces for Data Analysis) support
• Creating/Plotting the histogram, ntuple, profile and cloud
• Parameter optimization (Fitting)
  • you can constrain and/or fix parameters
  • parabolic and asymmetric error evaluation
  • various fitting methods are supported
    • including GA (Genetic Algorithm)
• XML based storing
• Matrix calculation

AIDA has already both C++ and Java implementations. Many analysis systems such as GEANT4, JAS3, OpenScientist, and Anaphe use AIDA.
