python拷贝文件到多个文件夹

主要用来做数据备份，每次用完以后再跑一次脚本，又可以将文件夹下的所有文件拷贝到指定的文件夹内

import os,sys,shutil;

class cur_env:
    path = sys.path[0]
    #print(path)
    os.chdir(path)

# copy files to multiple folders
class copyfiles:
    def __init__(self, psrc, pdst):
        self._src_path = psrc
        self._dst_path = pdst
        self._get_emails()
        self._get_folders()

    # get the log file list in the folder
    def _get_emails(self):
        files = os.listdir(self._src_path)
        self._file_list = [x for x in files if x.endswith('.log')]

    # get email account folders
    def _get_folders(self):
        temp = os.listdir(self._dst_path)
        self._folders = [x for x in temp if os.path.isdir(x)]
        

    # copy files to folders
    def copyfiles_to_folders(self):
        for folder in self._folders:
            for file in self._file_list:
                shutil.copy(self._src_path + '\\' + file,\
                            self._dst_path + '\\' + folder)

    # del files in dst folders
    def del_dst_files(self):
        for folder in self._folders:
            files = os.listdir(self._dst_path + '\\' + folder)
            for file in files:
                os.remove(self._dst_path + '\\'+folder+'\\'+file)


temp = copyfiles('C:\\Users\\sunyu\\Desktop\\emails',cur_env.path)    

我把数据备份在桌面的email文件夹内。有两个方法，一个是将文件全部拷贝到指定根目录下所有的文件夹内，另外一个是将指定根目录下所有文件夹内的文件清空。
