File close() Method in Python 3
The method close() closes the opened file. A closed file cannot be read or written any more.
Any operation, which requires that the file be opened will raise a ValueError
after the file has been closed. Calling close() more than once is allowed.
Python automatically closes a file when the reference
object of a file is reassigned to another file. It is a good practice to use the close()
method to close a file.
