使用python生成目录树

这是一个使用Python生成文件、目录树的程序,其中遇到一个问题是:如何确定某个目录下的某一文件是最后一个遍历的文件。因为最后一个遍历的文件前应添加"└─",非最后一个文件前添加"├─"。看了Python的API文档没有找到相关的系统函数。现在做法是:先统计出某个目录下的文件个数,在遍历目录时,当个数相等时,就可以确定该目录遍历结束。

import os

class dir(object):

def __init__(self):

self.SPACE = ""

self.list = []

def getCount(self, url):

files = os.listdir(url)

count = 0;

for file in files:

myfile = url + "//" + file

if os.path.isfile(myfile):

count = count + 1

return count

def getDirList(self, url):

files = os.listdir(url)

fileNum = self.getCount(url)

tmpNum = 0

for file in files:

myfile = url + "//" + file

size = os.path.getsize(myfile)

if os.path.isfile(myfile):

tmpNum = tmpNum +1

if (tmpNum != fileNum):

self.list.append(str(self.SPACE) + "├─" + file + "/n")

else:

self.list.append(str(self.SPACE) + "└─" + file + "/n")

if os.path.isdir(myfile):

self.list.append(str(self.SPACE) + "├─" + file + "/n")

# change into sub directory

self.SPACE = self.SPACE + "│ "

self.getDirList(myfile)

# if iterator of sub directory is finished, reduce "│ "

self.SPACE = self.SPACE[:-4]

return self.list

def writeList(self, url):

f = open(url, 'w')

f.writelines(self.list)

print "ok"

f.close()

if __name__ == '__main__':

d = dir()

d.getDirList("c:/windows") # input directory

d.writeList("c:/1.txt") # write to file
