从上述目录读取文件时出错（Python3.2）

Question

下面的代码

我在C:\TempFiles文件夹中保存了一个名为nd1.txt的记事本文档

import os,file,storage
database = file.dictionary()
tools = storage.misc()
lui = -1

def sendWord(wrd, findex):
    global lui
    if findex!=lui:
        tools.refreshRecentList()
        lui = findex
    if tools.mustIgnore(wrd)==0 and tools.toRecentList(wrd)==1:
        database.addWord(wrd,findex)        
def showPostingsList():
    database.display()

def parseFile(nfile, findex):
    for line in nfile:
        pl = line.split()
        for word in pl:
            print(word)
            sendWord(word.lower(),findex)

def parseDirectory():
    files = [open(f) for f in os.listdir('C:\TempFiles')]
    findex = 0
    for nf in files:
        parseFile(nf,findex)
        findex+=1

def main():
    parseDirectory()
    showPostingsList()

main()

现在每当我执行代码时，我都会得到以下错误消息

Traceback (most recent call last):
  File "E:\Documents\Information Retrieval\postingsList.py", line 39, in <module>
main()
  File "E:\Documents\Information Retrieval\postingsList.py", line 36, in main
parseDirectory(dirname)
  File "E:\Documents\Information Retrieval\postingsList.py", line 28, in parseDirectory
files = [open(f) for f in os.listdir('C:\TempFiles')]
  File "E:\Documents\Information Retrieval\postingsList.py", line 28, in <listcomp>
files = [open(f) for f in os.listdir('C:\TempFiles')]
FileNotFoundError: [Errno 2] No such file or directory: 'nd1.txt'

即使文件在上面提到的文件夹中，加上每个函数都正常工作，我还是用虚拟数据进行了检查

谁能告诉我我的代码哪里出错了吗？你知道吗

Answer 1

os.listdir提供文件名，而不是完整路径。您需要在调用open之前添加路径，最好使用os.path.join。你知道吗
