python目录更新

Question

from subprocess import call
import os

def consistence(sourcedir, destinationdir):
    sr = set(os.listdir(sourcedir))
    de = set(os.listdir(destinationdir))

    os.chdir(sourcedir)

    for i in sr.difference(de):
        call(('rm', '-rf', i))

    for i in sr.intersection(de):
        if os.path.isdir(i):
            consist(sourcedir + '/' + i, destinationdir + '/' + i)

    for i in de.difference(sr):
        call(('cp', '-r', destinationdir + '/' + i, sourcedir))

我想将两个目录更新，但是两个目录下的相同目录就不行，不能更新共有目录下的文件

#!/usr/bin/env python from subprocess import call import os import sys def consistency(sourcedir, destinationdir): sourcedir = unicode(sourcedir) destinationdir = unicode(destinationdir) sr = set(os.listdir(sourcedir)) de = set(os.listdir(destinationdir)) if not sr and not de: return os.chdir(sourcedir) for i in sr.difference(de): call(('rm', '-rf', i)) for i in sr.intersection(de): if os.path.isdir(sourcedir + '/' + i) and os.path.isdir(destinationdir + '/' + i): consistency(sourcedir + '/' + i, destinationdir + '/' + i) for i in de.difference(sr): call(('cp', '-r', destinationdir + '/' + i, sourcedir)) def main(): if len(sys.argv) > 3: print "Error: at most 3 arguments" print "Usage: consistency(source, destination)" return 1 sourcedir = sys.argv[1] destinationdir = sys.argv[2] consistency(os.path.abspath(sourcedir), os.path.abspath(destinationdir)) if __name__ == '__main__': main() 搞掂
