No such file or directory error

This is the error I am getting:

Traceback (most recent call last):
  File "E:stuffmodule.py", line 91, in <module>
    f = open('E:/stuff/log.txt')
IOError: [Errno 2] No such file or directory: 'E:/stuff/log.txt'

And this is my code:

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

The E:/stuff/log.txt file exists. I can navigate in Windows Explorer and open it so why can’t I open it?

EDIT:

Output of DIR command:

C:Documents and SettingsAdministrator>dir e:stuff
 Volume in drive E has no label.
 Volume Serial Number is 5660-4957

I am running the python script from the cmd like this:

python E:stuffmodule.py

Answer

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).
