python同步两个文件夹下的内容

本文实例为大家分享了python同步两个文件夹下的内容，供大家参考，具体内容如下

import os
import shutil
import time
import logging
import filecmp
#日志文件配置
log_filename ='synchro.log'
#日志输出格式化
log_format = '％(filename)s [％(asctime)s] [％(levelname)s] ％(message)s'
logging.basicConfig(format=log_format,datefmt='％Y-％m-％d ％H:％M:％S ％p',level=logging.DEBUG)
#日志输出到日志文件
fileLogger = logging.getLogger('fileLogger')
fh = logging.FileHandler(log_filename)
fh.setLevel(logging.INFO)
fileLogger.addHandler(fh);
#需要同步的文件夹路径,可以使用绝对路径,也可以使用相对路径
synchroPath1 = r'/home/xxx/image1'
synchroPath2 = r'/home/xxx/image2'

#同步方法
def synchro(synchroPath1,synchroPath2):
leftDiffList = filecmp.dircmp(synchroPath1,synchroPath2).left_only
rightDiffList = filecmp.dircmp(synchroPath1,synchroPath2).right_only
commondirsList =filecmp.dircmp(synchroPath1,synchroPath2).common_dirs
for item in leftDiffList:
 copyPath = synchroPath1 + '/' + item
 pastePath = synchroPath2 + '/' + item
 if(os.path.isdir(copyPath)):
  copyDir(copyPath,pastePath)
 else :
  shutil.copy2(copyPath,pastePath)
  fileLogger.info('copy '+copyPath +" to "+pastePath)
for item in rightDiffList:
 copyPath = synchroPath2 + '/' + item
 pastePath = synchroPath1 +'/' + item
 if(os.path.isdir(copyPath)):
  copyDir(copyPath,pastePath)
 else :
  shutil.copy2(copyPath,pastePath)
  fileLogger.info('copy '+copyPath +" to "+pastePath)
for item in commondirsList:
 copyPath = synchroPath2 + '/' + item
 pastePath = synchroPath1 +'/' + item
 syncDir(copyPath,pastePath)
#拷贝文件夹,如果文件夹不存在创建之后直接拷贝全部,如果文件夹已存在那么就同步文件夹  
def copyDir(copyPath,pastePath):
if(os.path.exists(pastePath)):
 synchro(copyPath,pastePath)
else :
 os.mkdir(pastePath)
 shutil.copytree(copyPath,pastePath)
#子文件夹左右两侧文件夹都包含,就同步两侧子文件夹
def syncDir(copyPath,pastePath):
 copyDir(copyPath,pastePath)
 copyDir(pastePath,copyPath)
while(True):
synchro(synchroPath1,synchroPath2)
logging.debug('synchro run')
#阻塞方法,上一步执行结束后等待五秒
time.sleep(5)

代码简单，但是不优雅，欢迎指正。
