Iterating Over Fixed-sized records

Instead of iterating over a file line by line, you want to iterate over a collection of fixed-sized records or chunks.

>>> from functools import partial
>>> SIZE = 32
>>> with open('somefile.data', 'rb') as f:
...     records in iter(partial(f.read, SIZE), b'')
...     for r in records:
...             # do sth.
For text files, reading line by line is more common.
For binary files, read fixed-sized records.
