The [[Heisenberg Uncertainty Principle|Heisenberg uncertainty principle]] for a particle does not allow a state in which the particle is simultaneously at a definite location and has also a definite momentum. Instead the particle has a range of momentum and spread in location attributable to quantum fluctuations.


Generally, a high-level interpreted scripting language is far not as fast as a compiled program. However, a specializing just-in-time compiler "Psyco"<ref>[http://psyco.sourceforge.net/ Psyco: High-level languages need not be slower than low-level ones.]</ref> runs existing Python programs much faster, with no change in the source text. In addition, the Python library contains a number of modules performing useful operations quite effectively. For example, "anydbm"<ref>[http://docs.python.org/release/2.5.2/lib/module-anydbm.html anydbm -- Generic access to DBM-style databases]</ref> can effectively maintain a large indexed file.

The Heisenberg uncertainty principle for a particle does not allow a state in which the particle is simultaneously at a definite location and has also a definite momentum. Instead the particle has a range of momentum and spread in location attributable to quantum fluctuations.

An uncertainty principle applies to most of quantum mechanical operators that do not commute (specifically, to every pair of operators whose commutator is a non-zero scalar operator).
