python怎么拷贝文件夹

1、拷贝文件夹

fromshutilimportcopytree,ignore_patterns
copytree(source,destination,ignore=ignore_patterns('*.pyc','tmp*'))

注：shutil.copytree实现

defcopytree(src,dst,symlinks=False,ignore=None):
names=os.listdir(src)
ifignoreisnotNone:
ignored_names=ignore(src,names)
else:
ignored_names=set()
os.makedirs(dst)
errors=[]
fornameinnames:
ifnameinignored_names:
continue
srcname=os.path.join(src,name)
dstname=os.path.join(dst,name)
try:
ifsymlinksandos.path.islink(srcname):
linkto=os.readlink(srcname)
os.symlink(linkto,dstname)
elifos.path.isdir(srcname):
copytree(srcname,dstname,symlinks,ignore)
else:
copy2(srcname,dstname)
#XXXWhataboutdevices,socketsetc.?
except(IOError,os.error)aswhy:
errors.append((srcname,dstname,str(why)))
#catchtheErrorfromtherecursivecopytreesothatwecan
#continuewithotherfiles
exceptErroraserr:
errors.extend(err.args[0])
try:
copystat(src,dst)
exceptWindowsError:
#can'tcopyfileaccesstimesonWindows
pass
exceptOSErroraswhy:
errors.extend((src,dst,str(why)))
iferrors:
raiseError(errors)

2、删除文件夹

#!/usr/bash/python
#encoding:utf-8
importos
importos.path
importstat
importshutil
classDelDir:
'''删除指定根目录下特定文件夹'''
def__init__(self,root,dirname):
self.root=root
self.dirname=dirname
defrun(self):
forr,dirs,filesinos.walk(self.root):
ifself.dirnameindirs:
srcDir=os.path.join(r,self.dirname)
#更改权限（win7会出现权限问题）
os.chmod(srcDir,stat.S_IREAD|stat.S_IWRITE)
result=shutil.rmtree(srcDir,False,self.__handler)
print"%s"%(srcDir)
def__handler(self,function,path,excinfo):
'''删除出错处理'''
#更改权限（win7会出现权限问题）
os.chmod(path,stat.S_IREAD|stat.S_IWRITE)
function(path)
print"[Handler]==>Path:%s\n\tHandlertheError:%s"%(path,excinfo)
if__name__=='__main__':
rootdir=r"E:\workspace\minioffice\mini-core\src\main\webapp"#需要处理的文件夹
rootdir=unicode(rootdir,"utf8")
dirname=".svn"#删除的文件夹
c=DelDir(rootdir,dirname)
c.run()
