Yes it is. After all that's how garbage collection works for all objects in Python, when nothing is using it, it gets deleted. But on a general note it's usually a bad idea to mix file descriptor and file object references to the same file at the same time. Things can get very confused at the OS level! Most things(everything?) you want to do with a file object can be done with a descriptor, albeit with a little more effort. Someone already showed you the lseek() function which saves you doing the conversion, I'd recommend keeping things in one format or the other.
