python - "file being used by another process" error message -

-

Yes, there are many other questions on this subject, I have seen the reactions but I have not seen any such useful solution gives.

I have a problem in its simplest form: 

  import os, time hfile = "status. Html" hf = open (hfile, "w") hf.write (Str (buf)) hf.close time.sleep (2) # Allow time to capture os.system (hfile) # File in the default browser

I get this error message : "The process can not access the file because it is being used by another process".

No other process is using it, because I can access it without error from another program, even if I run os.system (file) There is no point in using unlocker from the Python console

, as soon as I leave the program, I can open the html file in the browser, no complaints from the system.

This is not releasing the 'closed' file properly.

I run programs like this out of Pearl all the time, leaving a delay of 1 or 2 seconds without any problem.

Any suggestions?

You are not calling pass () . Must be: 

  import OS, time hfile = "condition .htm" hf = open (hfile, "w") hf.write (str (buf)) hf.close () # Note that parens time.sleep (2) # time to hold it os.system (hfile) # Run the html file in the default browser

However to avoid problems like this You must use the Reference Manager: 

  imported OS, with hfile = "positions.htm" open (hfile, 'w') as hf: hf.write (str (Buf) os.system (Hfile) # Run the html file in the default browser

References The Bh Manager will automatically be able to close the file.

For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
