in Python 2.5 document, os.remove() explain: On Windows, attempting to
remove a file that is in use causes an exception to be raised. but, i
run it in IDLE.it deletes my file that in use without any exception.

What do you mean by "in use"?

yes, i use this method,but actually the result don't agree with the Python's
manual. my OS is windows xp and version is simplified chinese!

There seems to be some misunderstanding.

zkfarmer, you said: "it deletes my file that in use without any exception."
Can you explain this sentence? How is your file "in use"?

zkfarmer, please try the following from your IDLE:

>>> myfilename = r"c:\tmp\test.txt"
>>> fh = open(myfilename, "w")
>>> fh.write("test\n")
>>> fh.close()
>>> fh = open(myfilename)
>>> import os
>>> os.remove(myfilename)

Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    os.remove(myfilename)
WindowsError: [Error 32] The process cannot access the file because it
is being used by another process: 'c:\\tmp\\test.txt'
>>> 

...and copy here what happened.

Thanks!

Thank you for your reply.I mean I used gvim to open a file. the Python
manual did not specify how to use a file, but said that if a file is to be
used, the deletion of the file will be exception to be raise.so when I use
gvim to open a file, then run os.remove () method to remove the file, the
file is deleted, and no exception to be raise.

Editors usually don't cause the file to be "in use." "In use" would 
mean that the file was being held open by a program. Editors only do 
that when they are opening or saving a file.

Thanks, you are right, I am wrong, I think that is the use of editing, so I
made a mistake.

Can a file be "in use" other than being opened? If not, wouldn't be
"opened" be a better wording?

I can't understand you. Could you explain more?

Well, you seemed to be misled by the wording "in use". Therefore, I
propose to change "in use" to "opened", but only if "in use" always
means "opened".
