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))

1. 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')
