1、拷贝文件夹
from shutil import copytree, ignore_patterns copytree(source, destination, ignore=ignore_patterns('*.pyc', 'tmp*'))
注:shutil.copytree实现
def copytree(src, dst, symlinks=False, ignore=None): names = os.listdir(src) if ignore is not None: ignored_names = ignore(src, names) else: ignored_names = set() os.makedirs(dst) errors = [] for name in names: if name in ignored_names: continue srcname = os.path.join(src, name) dstname = os.path.join(dst, name) try: if symlinks and os.path.islink(srcname): linkto = os.readlink(srcname) os.symlink(linkto, dstname) elif os.path.isdir(srcname): copytree(srcname, dstname, symlinks, ignore) else: copy2(srcname, dstname) # XXX What about devices, sockets etc.? except (IOError, os.error) as why: errors.append((srcname, dstname, str(why))) # catch the Error from the recursive copytree so that we can # continue with other files except Error as err: errors.extend(err.args[0]) try: copystat(src, dst) except WindowsError: # can't copy file access times on Windows pass except OSError as why: errors.extend((src, dst, str(why))) if errors: raise Error(errors)
2、删除文件夹
#! /usr/bash/python # encoding:utf-8 import os import os.path import stat import shutil class DelDir: ''' 删除指定根目录下特定文件夹 ''' def __init__(self, root, dirname): self.root = root self.dirname = dirname def run(self): for r, dirs, files in os.walk(self.root): if self.dirname in dirs: 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\tHandler the Error: %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()
