Faster According to a couple of simple benchmark, Python 2.3 is about 20-30% faster than Python 2.2.3. Some of this speed-up was obtained by removing the SET_LINENO opcodes, which means that the difference is less impressive when comparing "python -O"; the rest was various careful tune-ups. New Tools A brand new version of IDLE (from the IDLEfork project at SourceForge) is now ...

The C code in MMTK was written from scratch in the form of Python extension modules that only handle the few time-critical aspects: evaluation of interaction energies, and long-running iterative algorithms such as energy minimization and Molecular Dynamics, which run without any Python-related overhead. Extensive use is made of Numerical Python, LAPACK, and the netCDF library. MMTK provides multi-threading support for share...

  • Comparing Python to Other Languages

    ...Python; Python can also be used to prototype components until their design can be "hardened" in a Java implementation. To support this type of development, a Python implementation written in Java is under development, which allows calling Python code from Java and vice versa. In this implementation, Python source code is translated to Java bytecode (with help from a run-time library to support Python's dynamic semantics). Javascript Python's "object-based" subset is roughly equivalen...
