# vim: set fileencoding=utf-8 : # ***********************IMPORTANT NMAP LICENSE TERMS************************ # * * # * The Nmap Security Scanner is (C) 1996-2015 Insecure.Com LLC. Nmap is * # * also a registered trademark of Insecure.Com LLC. This program is free * # * software; you may redistribute and/or modify it under the terms of the * # * GNU General Public License as published by the Free Software * # * Foundation; Version 2 ("GPL"), BUT ONLY WITH ALL OF THE CLARIFICATIONS * # * AND EXCEPTIONS DESCRIBED HEREIN. This guarantees your right to use, * # * modify, and redistribute this software under certain conditions. If * # * you wish to embed Nmap technology into proprietary software, we sell * # * alternative licenses (contact sales@nmap.com). Dozens of software * # * vendors already license Nmap technology such as host discovery, port * # * scanning, OS detection, version detection, and the Nmap Scripting * # * Engine. * # * * # * Note that the GPL places important restrictions on "derivative works", * # * yet it does not provide a detailed definition of that term. To avoid * # * misunderstandings, we interpret that term as broadly as copyright law * # * allows. For example, we consider an application to constitute a * # * derivative work for the purpose of this license if it does any of the * # * following with any software or content covered by this license * # * ("Covered Software"): * # * * # * o Integrates source code from Covered Software. * # * * # * o Reads or includes copyrighted data files, such as Nmap's nmap-os-db * # * or nmap-service-probes. * # * * # * o Is designed specifically to execute Covered Software and parse the * # * results (as opposed to typical shell or execution-menu apps, which will * # * execute anything you tell them to). * # * * # * o Includes Covered Software in a proprietary executable installer. The * # * installers produced by InstallShield are an example of this. Including * # * Nmap with other software in compressed or archival form does not * # * trigger this provision, provided appropriate open source decompression * # * or de-archiving software is widely available for no charge. For the * # * purposes of this license, an installer is considered to include Covered * # * Software even if it actually retrieves a copy of Covered Software from * # * another source during runtime (such as by downloading it from the * # * Internet). * # * * # * o Links (statically or dynamically) to a library which does any of the * # * above. * # * * # * o Executes a helper program, module, or script to do any of the above. * # * * # * This list is not exclusive, but is meant to clarify our interpretation * # * of derived works with some common examples. Other people may interpret * # * the plain GPL differently, so we consider this a special exception to * # * the GPL that we apply to Covered Software. Works which meet any of * # * these conditions must conform to all of the terms of this license, * # * particularly including the GPL Section 3 requirements of providing * # * source code and allowing free redistribution of the work as a whole. * # * * # * As another special exception to the GPL terms, Insecure.Com LLC grants * # * permission to link the code of this program with any version of the * # * OpenSSL library which is distributed under a license identical to that * # * listed in the included docs/licenses/OpenSSL.txt file, and distribute * # * linked combinations including the two. * # * * # * Any redistribution of Covered Software, including any derived works, * # * must obey and carry forward all of the terms of this license, including * # * obeying all GPL rules and restrictions. For example, source code of * # * the whole work must be provided and free redistribution must be * # * allowed. All GPL references to "this License", are to be treated as * # * including the terms and conditions of this license text as well. * # * * # * Because this license imposes special exceptions to the GPL, Covered * # * Work may not be combined (even as part of a larger work) with plain GPL * # * software. The terms, conditions, and exceptions of this license must * # * be included as well. This license is incompatible with some other open * # * source licenses as well. In some cases we can relicense portions of * # * Nmap or grant special permissions to use it in other open source * # * software. Please contact fyodor@nmap.org with any such requests. * # * Similarly, we don't incorporate incompatible open source software into * # * Covered Software without special permission from the copyright holders. * # * * # * If you have any questions about the licensing restrictions on using * # * Nmap in other works, are happy to help. As mentioned above, we also * # * offer alternative license to integrate Nmap into proprietary * # * applications and appliances. These contracts have been sold to dozens * # * of software vendors, and generally include a perpetual license as well * # * as providing for priority support and updates. They also fund the * # * continued development of Nmap. Please email sales@nmap.com for further * # * information. * # * * # * If you have received a written license agreement or contract for * # * Covered Software stating terms other than these, you may choose to use * # * and redistribute Covered Software under those terms instead of these. * # * * # * Source is provided to this software because we believe users have a * # * right to know exactly what a program is going to do before they run it. * # * This also allows you to audit the software for security holes. * # * * # * Source code also allows you to port Nmap to new platforms, fix bugs, * # * and add new features. You are highly encouraged to send your changes * # * to the dev@nmap.org mailing list for possible incorporation into the * # * main distribution. By sending these changes to Fyodor or one of the * # * Insecure.Org development mailing lists, or checking them into the Nmap * # * source code repository, it is understood (unless you specify otherwise) * # * that you are offering the Nmap Project (Insecure.Com LLC) the * # * unlimited, non-exclusive right to reuse, modify, and relicense the * # * code. Nmap will always be available Open Source, but this is important * # * because the inability to relicense code has caused devastating problems * # * for other Free Software projects (such as KDE and NASM). We also * # * occasionally relicense the code to third parties as discussed above. * # * If you wish to specify special license conditions of your * # * contributions, just say so when you send them. * # * * # * This program is distributed in the hope that it will be useful, but * # * WITHOUT ANY WARRANTY; without even the implied warranty of * # * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the Nmap * # * license file for more details (it's in a COPYING file included with * # * Nmap, and also available from https://svn.nmap.org/nmap/COPYING) * # * * # ***************************************************************************/ import math class PolarCoordinate: """ Class to implement a polar coordinate object """ def __init__(self, r=0, t=0): """ Constructor method of PolarCoordinate class @type r: number @param r: The radius of coordinate @type t: number @param t: The angle (theta) of coordinate in radians """ self.__r = r """Radius of polar coordinate""" self.__t = t """Angle (theta) of polar coordinate in radians""" def get_theta(self): """ """ return math.degrees(self.__t) def get_radius(self): """ """ return self.__r def set_theta(self, t): """ """ self.__t = math.radians(t) def set_radius(self, r): """ """ self.__r = r def get_coordinate(self): """ Set polar coordinate @rtype: tuple @return: Polar coordinates (r, t) """ return (self.__r, math.degrees(self.__t)) def set_coordinate(self, r, t): """ Set polar coordinate @type r: number @param r: The radius of coordinate @type t: number @param t: The angle (theta) of coordinate """ self.__r = r self.__t = math.radians(t) def to_cartesian(self): """ Convert polar in cartesian coordinate @rtype: tuple @return: cartesian coordinates (x, y) """ x = self.__r * math.cos(self.__t) y = self.__r * math.sin(self.__t) return (x, y) class CartesianCoordinate: """ Class to implement a cartesian coordinate object """ def __init__(self, x=0, y=0): """ Constructor method of CartesianCoordinate class @type x: number @param x: The x component of coordinate @type y: number @param y: The y component of coordinate """ self.__x = x """X component of cartesian coordinate""" self.__y = y """Y component of cartesian coordinate""" def get_coordinate(self): """ Get cartesian coordinate @rtype: tuple @return: Cartesian coordinates (x, y) """ return (self.__x, self.__y) def set_coordinate(self, x, y): """ Set cartesian coordinate @type x: number @param x: The x component of coordinate @type y: number @param y: The y component of coordinate """ self.__x = x self.__y = y def to_polar(self): """ Convert cartesian in polar coordinate @rtype: tuple @return: polar coordinates (r, t) """ r = math.sqrt(self.__x ** 2 + self.__y ** 2) if self.__x > 0: if self.__y >= 0: t = math.atan(self.__y / self.__x) else: t = math.atan(self.__y / self.__x) + 2 * math.pi elif self.__x < 0: t = math.atan(self.__y / self.__x) + math.pi elif self.__x == 0: if self.__y == 0: t = 0 if self.__y > 0: t = math.pi / 2 else: t = -math.pi / 2 return (r, t) if __name__ == "__main__": # Testing application polar = PolarCoordinate(1, math.pi) cartesian = CartesianCoordinate(-1, 0) print polar.to_cartesian() print cartesian.to_polar()
