There are reading and writing permissions.

Answer 2

+1 A:

Since it is windows, and the backslash is a escape character, you must double the backslash to escape it. Try

e:\\stuff\\log.txt

Rawheiser 2010-10-23 14:04:40

Why not use r"e:\stuff\log.txt"? Why not use `os.path.join( "E:", "stuff", "log.txt" )`?

S.Lott 2010-10-23 14:15:25

OP is using forward slashes - escaping is _not_ an issue here. As brady and Tim rightly point out, the `log.txt` file does _not_ exist, it's `log.txt.txt`.

Answer 3

+1 A:

it been a long time that i didn't use windows, but if i remember well windows use back-slash in system path so you should do:

import os

file_name = os.path.join("e:\\stuff", "log.txt")

f = open(file_name)

and not:

f = open('E:/stuff/log.txt')

there is not / in paths in windows.

Python does actually handle forward slashes okay - it may not have when you used it, I don't know how long ago that was :-)

paxdiablo 2010-10-23 14:36:26

@paxdiablo: excuse me ? i didn't understand, i said that windows don't use backslash in path like unix. when did i said that python doesn't handle forward slash ?

singularity 2010-10-23 14:41:42

You said not to use `f = open('E:/stuff/log.txt')` when in fact that will work fine. You don't need backslashes.

paxdiablo 2010-10-23 14:51:13

@paxdiablo:correct me if i'm wrong, but i think that windows don't have path like this __E:/stuff/log.txt__ no forward slash, they use backslash like this : __E:\stuff\log.txt__ , you see the difference :)

singularity 2010-10-23 15:04:10

Yes I see the difference but Windows itself handles this as per http://msdn.microsoft.com/en-us/library/aa365247%28VS.85%29.aspx#paths : "Note File I/O functions in the Windows API convert "/" to "\" as part of converting the name to an NT-style name, except when using the "\\?\" prefix as detailed in the following sections." You can see this in the question. The code used forward slash but the error message used backslash.

paxdiablo 2010-10-23 15:10:57

@paxdiablo : ahh ok, thank you very much for the info, like i said it's been a long time that i didn't use windows :), and so windows normalize the path without the need to call : os.path.normpath() , heh !!

Answer 4

+2 A:

Firstly, from above, Windows supports / just fine.

Secondly: Well, if you look at your file, you'll notice it's not log.txt, it's log.txt.txt... You may see it as "log.txt" in your graphical folder viewer (as opposed to the CLI "dir" command) simply because it hides the known file extensions.

I recommend you disable this - see folder options, there should be an option "Hide extensions of known file types" (or similar).

Answer 5

+1 A:

Define you path names using os.path.join()

root="E:\\"
mylog = os.path.join(root,"stuff","log.txt") # or log.txt.txt as seen in your dir output
f = open(mylog)
...
f.close()

Answer 6

+3 A:

Look at this line in the "dir" output:

23. 10. 2010  15:47                 0 log.txt.txt

The file you are looking for is named "log.txt.txt", not "log.txt". I see this happen when people set up the Windows file manager to not show known file extensions and then they try to add or modify an extension. I recommend to others that they turn this behavior off. You can do this under View->Folder Options I believe.
