Mi spiegate per favore come si utilizzano i file in formato python?Ho provato ad esegurli ma non succede niente...Devo utlizzare questo programma:
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, self._intervalEnds))
t = self._intervalBegins
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")
# initialise
optParser = OptionParser()
optParser.add_option("-v", "--verbose", action="store_true", dest="verbose",
default=False, help="tell me what you are doing")
# i/o
optParser.add_option("-1", "--dump1", dest="dump1",
help="First dump (mandatory)", metavar="FILE")
optParser.add_option("-2", "--dump2", dest="dump2",
help="Second dump (mandatory)", metavar="FILE")
optParser.add_option("-o", "--output", dest="output",
help="Name for the output", metavar="FILE")
optParser.add_option("-e", "--exclude", dest="exclude",
help="Exclude these values from being changed (stay as in 1)", metavar="FILE")
# parse options
(options, args) = optParser.parse_args()
parser = make_parser()
# read dump1
if options.verbose:
print "Reading dump1..."
weights1 = WeightsReader()
parser.setContentHandler(weights1)
parser.parse(options.dump1)
# read dump2
if options.verbose:
print "Reading dump2..."
weights2 = WeightsReader()
parser.setContentHandler(weights2)
parser.parse(options.dump2)
# process
if options.verbose:
print "Computing mean..."
exclude = []
if options.exclude:
exclude = options.exclude.split(",")
weights1.mean(weights2, exclude)
# save
if options.verbose:
print "Writing..."
weights1.write(options)
grazie a tutti!
