It incorporates modules, exceptions, dynamic typing, very +high level dynamic data types, and classes. Python combines +remarkable power with very clear syntax. It has interfaces to many +system calls and libraries, as well as to various window systems, and +is extensible in C or C++. It is also usable as an extension language +for applications that need a programmable interface. Finally, Python +is portable: it runs on many brands of UNIX, on the Mac, and on +MS-DOS. + +As a short example of what Python looks like, here's a script to +print prime numbers (not blazingly fast, but readable!). When this +file is made executable, it is callable directly from the UNIX shell +(if your system supports #! in scripts and the python interpreter is +installed at the indicated place). + +#!/usr/local/bin/python + +# Print prime numbers in a given range + +def main(): + import sys + min, max = 2, 0x7fffffff + if sys.argv[1:]: + min = int(eval(sys.argv[1])) + if sys.argv[2:]: + max = int(eval(sys.argv[2])) + primes(min, max) + +def primes(min, max): + if 2 >= min: print 2 + primes = [2] + i = 3 + while i <= max: + for p in primes: + if i%p == 0 or p*p > i: break + if i%p <> 0: + primes.append(i) + if i >= min: print i + i = i+2 + +main() |
