Salve, devo utilizzare alcuni file scritti in Python ma non so veramente cosa bisongna fare.Ho provato a cliccare sul file ma dopo la schermata nera si chiude tutto.Aprendo con IDLE vedo il codice del programma, ma cmq come faccio ad utilizzarlo??Grazie mille vi posto il codice:
import os, string, sys
from optparse import OptionParser
from xml.sax import saxutils, make_parser, handler
from datetime import datetime
class WeightsReader(handler.ContentHandler):
"""Reads the dump file"""
def __init__(self):
self._id = ''
self._edgeValues = {}
self._intervalBegins = []
self._intervalEnds = []
def startElement(self, name, attrs):
if name == 'interval':
self._beginTime = int(attrs['begin'])
self._intervalBegins.append(self._beginTime)
self._intervalEnds.append(int(attrs['end']))
self._edgeValues[self._beginTime] = {}
if name == 'edge':
self._id = attrs['id']
self._edgeValues[self._beginTime][self._id] = {}
for attr in attrs.getQNames():
if attr!="id":
self._edgeValues[self._beginTime][self._id][attr] = float(attrs[attr])
def sub(self, weights, exclude):
for t in self._edgeValues:
for e in self._edgeValues[t]:
for a in self._edgeValues[t][e]:
if a not in exclude:
self._edgeValues[t][e][a] = (self._edgeValues[t][e][a] + weights._edgeValues[t][e][a]) / 2.
def write(self, options):
fd = open(options.output, "w")
fd.write("<?xml version=\"1.0\"?>\n\n")
fd.write("<!-- generated on %s by netdumpdiv.py \n" % datetime.now())
fd.write(" -1 %s\n" % options.dump1)
fd.write(" -2 %s\n" % options.dump2)
fd.write(" -o %s\n" % options.output)
fd.write("-->\n\n")
fd.write("<netstats>\n")
for i in range(0, len(self._intervalBegins)):
fd.write(" <interval begin=\"%s\" end=\"%s\">\n" % (self._intervalBegins[i], self._intervalEnds[i]))
t = self._intervalBegins[i]
for e in self._edgeValues[t]:
fd.write(" <edge id=\"%s\"" % e)
for a in self._edgeValues[t][e]:
fd.write(" %s=\"%s\"" % (a, self._edgeValues[t][e][a]))
fd.write("/>\n")
fd.write(" </interval>\n")
fd.write("</netstats>\n")
