An idiom of Python is to use the with statement:
with open(filename, "r") as f:
# some code that operates on f
pass
# when this code block exists, the `with` statement will automatically close the file `f`
# file is now closed. The variable `f` will still point at an object, but it can not be operated upon
>>> f
<_io.TextIOWrapper name='file_f' mode='r' encoding='UTF-8'>
>>> f.readlines()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: I/O operation on closed file.
>>> f.closed
True
>>> f.__sizeof__()

If you need to delete the object entirely use del f.
