The Zen of Python has a lot of wisdom to offer. One especially useful idea is that "There should be one-and preferably only one-obvious way to do it." Yet there are multiple ways to do most things in Python, and often for good reason. For example, there are multiple ways to read a file in Python, including the rarely used mmap module.
Python's mmap provides memory-mapped file input and output (I/O). It allows you to take advantage of lower-level operating system functionality to read files as if they were one large string or array. This can provide significant performance improvements in code that requires a lot of file I/O.
In this video course, you'll learn

What problems you can solve with mmap
How use memory mapping to read large files faster
How to change a portion of a file without rewriting the entire file
How to use mmap to share information between multiple processes
