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')
