实现python代码的动态删除多余的日志文件（非自带滚动日志方法）

import os
from os.path import join,getsize

size=0L
for root,dirs,files in os.walk(dir):
size+=sum([getsize(join(root,name)) for name in files])
return size/1024/1024

MaxSize=10240
if sumSize>=MaxSize:

#print fileName
while(sumSize>=MaxSize):
name=fileName.pop(0)
#print name
os.popen('rm -rf ' + dir+'/'+ name)

#print sumSize
if __name__ == '__main__':
