What you would learn in Python mmap: Doing File I/O With Memory Mapping course?
The Zen of Python has many wisdom points to share. One beneficial concept is "There should be one--and preferably only one--obvious way to do it." However, there are many methods to accomplish most tasks in Python, often for good reasons. For instance, there are a variety of ways to read files in Python as well as the less utilized the mmap module.
The Python mmap allows memory-mapped files with input as well as output (I/O). It lets you make use of the lower-level features of the operating system for reading files, an array, or one big string. This can result in significant performance enhancements in programs that require large amounts of file-related I/O.
