Exercise: generator
Take the two generator examples (increment number and Fibonacci) and change them to provide infinite iterations. Then try to run them in a for loop. Just make sure you have some other condition to leave the for-loop.
## Exercise: Binary file reader {id: exercise-binary-file-reader}
Create a generator that given a filename and a number n will return the content of the file in chunks of n characters.
## Exercise: File reader with records {id: exercise-file-reader-with-records}
In a file we have "records" of data. Each record starts with three bytes in which we have the length of the record. Then the content.
`` 8 ABCDEFGH 5 XYZQR ``
Given this source file

using this code

we can create this file:

The exercise is to create an iterator/generator that can read such a file record-by-record.
