#44737 — Python not starting

I was using python from over an year and half.Suddenly from yesterday i'm unable to run it.
The error is as follows
Traceback (most recent call last):

    main()
  File "C:\Python27\lib\site.py", line 546, in main

Just a wild guess, but did you happen to create a module of your own 
named "stat", which is getting imported instead of the one from the 
library?

Try doing:

>>> print stat.__file__

and see what it says.

I don't know Windows, but my guess is still that it's finding some other 
file called stat.py before it's finding the system library one.  Try 
doing a file system search for all files named "stat.py" and see what 
you find.  On unix, I would do "find / -name stat.py".  I assume there's 
something similar on Windows.

The other thing I would try is tracing the python process as it starts 
up.  On unix, I would do something like "strace -e trace=file python" 
and see if it's finding a stat.py in some unexpected place.  Again, I 
can only assume there's something similar on Windows.

Oh, and please don't post with Google Groups.  It double-spaces 
everything and makes your message really difficult to read.

Or alternatively, disable site.py by invoking python -S, and then
manually import stat and see what its file is.

Here's the steps:

1) Start Python with the -S option. You have apparently figured this
part out. This should give you a working interactive Python.

2) Type:
import stat
stat.__file__

3) See what the file is that was named there. If you created it, you
now know the problem.

4) Read Mark Lawrence's signature.

This post adds nothing to what has already been said; it's just
coalescing the previously-given advice into exact steps.

Chris i have seen stat.__file__. It gives me 'C:\\Python27\\lib\\stat.pyc'. What should i do now.

Place the call to print stat.__file__ in the file genericpath.py 
immediately before the line that gives the attribute error.

Would you also be kind enough to read and use the guidance given in the 
link in my signature.  My eyesight is bad enough without parsing double 
spaced stuff courtesy of google groups, thanks.

I don't mean to be disrespectful, but did you actually read the page you 
were asked to read?  It says, about halfway down the page, "You should 
remove the excess quoted blank lines before posting. There are several 
way to do this.", and then goes on to describe three different ways.

If you read that page, you'll know that it does NOT advocate the total
elimination of quoted text, which is what you've now done. Please
don't. Your posts now lack any form of context.

Sorry ChrisA,not only him for all, for the mess i have created.It was the first time for me on google groups. 
I am very happy to inform all of you that the problem is solved. The problem was due to the prescence of duplicates for genericpath.pyc and stat.pyc.I have deleted them and new ones were generated as i started python.
Thanking all of you for assisting me in solving the issue.

Excellent! Glad it's sorted.

The .pyc problem is, if I understand correctly, more permanently
solved in newer versions of Python. So this won't ever be an issue
again :)

Well, I'm glad it's sorted, but the solution raises as many questions as 
it answers.

How did you get duplicate genericpath.pyc and stat.pyc files?

If they were duplicates, why didn't they have the right code in them?

It's probably not worth spending any more time investigating, but it is 
still rather mysterious.

When i was running idle on 4th of May,some error came out saying Idle sub-process error i don't remember it correctly,but i wonder how my windows box kept both the files and always loaded the older one instead of new one :D.

Well, the obvious question is, what did you do yesterday to change your 
system? Did you install any new packages? Run a Windows update? Delete 
some stuff? Something changed. What was it?

This is a Python error, so Python is definitely starting. It's starting, 
hitting an error, and then failing with an exception.

Interestingly, the error is in os.path.isdir. The os module should be 
importing the ntpath module. The ntpath module tries to import _isdir 
from the nt module, and if that fails, falls back on genericpath.isdir. 
Which is what fails. So you have two problems:

- why is your nt module missing?

- why does genericpath.isdir fail?


Try running Python from the command line with the -S switch:


python -S


(you might need to use /S on Windows instead, I'm not sure.) Note that 
this is uppercase S, not lowercase. -S will disable the import of site.py 
module, which hopefully will then give you a prompt so you can run this:


import nt
print nt.__file__


which hopefully will show you have created a file called "nt.py" which is 
interfering with the actual nt file needed by Python. Get rid of that, 
and you should be right.

That is only a convention among Microsoft's CLI utilities. Very few others follow it (even for programs written specifically for Windows),
and it is certainly not a necessity on Windows.
