The basic [`for`][for statement] `loop` in Python is better described as a _`for each`_ which cycles through the values of any [iterable object][iterable], terminating when there are no values returned from calling [`next()`][next built-in] (_raising a [`StopIteration`][stopiteration]_).

- [`while`][while-loops] loops are used for _indefinite_ (uncounted) iteration.
- [`for`][for-loops] loops are used for _definite_ (counted) iteration.
- The keywords [`break` and `continue`][control flow] help customize loop behavior.
- [`range(<start>, stop, <step>)`][range] can be used to generate a sequence for a loop counter.
- [`range(<start>, <stop>, <step>)`][range] can be used to generate a sequence for a loop counter.
- The built-in [`enumerate()`][enumerate] will return (`<value>`, `<index>`) pairs to iterate over.

Also being familiar with the following can help with completing the tasks:

- [`lists`][list]: indexing, nested lists, [`<list>.append`][append and pop], [`<list>.pop()`][append and pop].
- [`lists`][list]: indexing, nested lists, [`<list>.append()`][append and pop], [`<list>.pop()`][append and pop].
- [`str`][str]: `str()` constructor, using the `+` to concatenate strings, optionally, [`f-strings`][f-strings].

## 2. Non-Passing Students

- There's no need to declare `loop` counters or `index` counters when iterating through an object using a `for` loop.
- A results counter does need to be set up and _incremented_ -- you'll want to `return` the count of non-passing students when the loop terminates.
