尝试打开现有文件时出现 IOError [英] IOError when trying to open existing files

问题描述

我编写的用于从特殊文本文件中提取一些信息的 Python 程序有一个小问题.循环(下面的代码)需要执行我的函数 extract_zcoords() 超过 500 个文件(1 个文件给出一个列表)，以便我可以构建数据集.

I have a small issue with a python program that I wrote to extract some information from a special text file. The loop (code below) needs to execute my function extract_zcoords() over 500 files (1 file gives one list) so that I can build a dataset.

import os

def extract_zcoord(filename): 
    f = open(filename, 'r')         
    ... # do something with f


### LOOP OVER DIRECTORY 
location = '/Users/spyros/Desktop/3NY8MODELSHUMAN/HomologyModels' 

for filename in os.listdir(location):
    extract_zcoord(filename)

错误:IOException No such file or directory 是发生的那个，所以由于某种原因 python 没有访问这些文件.我检查了目录路径名(位置)和文件权限，它们是正确的(读+写).当文件确实存在且路径名正确时，为什么会报告 IOError 任何想法?

---

THE ERROR: The IOException No such file or directory is the one that occurs, so for some reason python is not accessing the files. I have checked directory pathname (location) and file permissions, and they are correct (read+write). Any ideas why an IOError would be reported when the files do exist and pathname is correct?

任何想法可能是错误的?

Any ideas what might be wrong?

推荐答案

需要将目录名和文件名连成一个完整路径:

You need to join the dirname and filename into one complete path:

location = '/Users/spyros/Desktop/3NY8MODELSHUMAN/HomologyModels' 
for filename in os.listdir(location):
    filename = os.path.join(location, filename)
