FILES
File is a named location on disk to store related information. It is used to
permanently store data in a non-volatile memory (e.g. hard disk).
When we want to read from or write to a file we need to open it first. When we
are done, it needs to be closed, so that resources that are tied with the file are
freed. Hence, in Python, a file operation takes place in the following order.
1. Open a file
2. Read or write (perform operation)
3. Close the file
