I am trying to open a file in 'w' mode open('file', 'wb'). open() will throw with IOError with errno 13 if the file is locked by another application or if user does not have permission to open/write to the file. 

How can I distinguish these two cases ? Namely, if some application has the file open or not. 

Thanks,
nomadali
