python目录递归遍历程序

Question

我的程序不相信文件夹是目录,假设它们是文件,并且因此,递归将文件夹打印为文件,然后由于没有等待遍历的文件夹,程序结束.

import os
import sys
class DRT:
    def dirTrav(self, dir, buff):
        newdir = []
        for file in os.listdir(dir):
            print(file)
            if(os.path.isdir(file)):
                newdir.append(os.path.join(dir, file))
        for f in newdir:
            print("dir: " + f)
            self.dirTrav(f, "")
dr = DRT()
dr.dirTrav(".", "")

Answer 1

从那里看os.walk:

此示例显示起始目录下每个目录中的非目录文件占用的字节数,但它不在任何CVS子目录下查看:

import os
from os.path import join, getsize
for root, dirs, files in os.walk('python/Lib/email'):
    print root, "consumes",
    print sum(getsize(join(root, name)) for name in files),
    print "bytes in", len(files), "non-directory files"
    if 'CVS' in dirs:
        dirs.remove('CVS')  # don't visit CVS directories
