• Python Success Stories

  Python Success Stories Background The Molecular Modeling Toolkit (MMTK) is a open source Python library for molecular modeling and simulation with a focus on biomolecular systems, written in a mixture of Python and C. It provides standard techniques such as Molecular Dynamics or normal mode calculations in a ready-to-use form, but also provides a basis of low-level operations on top of which new techniques can easily be implemented. I started developing MMTK in 1996. I had some experience wit...

  Notes Python 2.1.3 Release Notes Release date: 08-April-2002 What's new in Python 2.1.3 (final)? Core Fixed two bugs reported as SF #535905: under certain conditions, deallocating a deeply nested structure could cause a segfault in the garbage collector, due to interaction with the "trashcan" code; access to the current frame during destruction of a local variable could access a pointer to freed memory. SF #457466: popenx() argument mangling hangs python (win9x only). Under certa...

• Python 2.4.1 - Release Notes

  ...multi-threaded applications which try to be highly responsive, response time will increase by some (perhaps imperceptible) amount. When multiplying very large integers, a version of the so-called Karatsuba algorithm is now used. This is most effective if the inputs have roughly the same size. If they both have about N digits, Karatsuba multiplication has O(N**1.58) runtime (the exponent is log_base_2(3)) instead of the previous O(N**2). Measured results may be better or worse than that, depe...
