python学习笔记

1. 查看模块帮助
2. Windows下文件和文件夹的处理

3. 查看文件夹下所有文件的总大小，包括子目录的递归

   import os
   sizeList = []
   #
   def get_size(path):
   fileList = os.listdir(path)
   for filename in fileList:
       pathTemp = os.path.join(path, filename)
       if os.path.isdir(pathTemp):
           get_size(pathTemp)
       elif os.path.isfile(pathTemp):
           fileSize = os.path.getsize(pathTemp)
           print('Directory %s size is : %d' %(pathTemp, fileSize))
           sizeList.append(fileSize)       
   #
   path = input("please input path: ").strip()
   get_size(path)
   print("all size is :%d bytes" % sum(sizeList))

4. copy文件夹
   例：将test目录下的所有文件拷贝到目录test1下

   import shutil, os
   os.chdir('d:\\')
   shutil.copytree('d:\\test', 'd:\\test1')
