Built-in open() with buffering > 1

[Ramchandra Apte]

`f._CHUNK_SIZE = 5` is modifying Python's internal variables - don't do that
google buffering to find out what it is
buffering is how much Python will keep in memory
f.read(1) will actually read `buffering` bytes of memory so that when you read later, the reading can be done from memory
