本文實例講述了Python實現拷貝 刪除文件夾的方法。分享給大家供大家參考，具體如下：

1. 拷貝文件夾

from shutil import copytree, ignore_patternscopytree(source, destination, ignore=ignore_patterns('*.pyc', 'tmp*'))

注：shutil.copytree實現

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. 刪除文件夾

#! /usr/bash/python# encoding:utf-8import osimport os.pathimport statimport shutilclass DelDir: ''' 刪除指定根目錄下特定文件夾 ''' 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)  #更改權限（win7會出現權限問題）  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): ''' 刪除出錯處理 ''' #更改權限（win7會出現權限問題） 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" # 需要處理的文件夾 rootdir = unicode(rootdir, "utf8") dirname = ".svn" # 刪除的文件夾 c = DelDir(rootdir, dirname) c.run()

Python實現文件夾遞歸拷貝

目標：

1.多層文件夾嵌套，在要備份的文件夾中嵌套多個文件夾

2.增量備份，因為文件較多，且之前已有部分備份，所以只需對新增的文件進行備份，提升效率

Python安裝：

1.下載安裝包，http://www.python.org/getit/，可以選擇Python2或3，2的兼容性更好

2.添加Python安裝目錄如D:/Program/Python到環境變量Path中
