# Hints
|
|
|
|
## General
|
|
|
|
## 1. Tracking Poker Rounds
|
|
|
|
- Lists in Python may be [constructed][constructed] in multiple ways.
|
|
- This function should [return][return] a `list`.
|
|
|
|
## 2. Keeping all Rounds in the Same Place
|
|
|
|
- Sequence types such as `list` support [common operations][common sequence operations].
|
|
- This function should [return][return] a `list`.
|
|
|
|
## 3. Finding Prior Rounds
|
|
|
|
- Sequence types such as `list` support a few [common operations][common sequence operations].
|
|
- This function should [return][return] a `bool`.
|
|
|
|
## 4. Averaging Card Values
|
|
|
|
- To get the average, this function should count how many items are in the `list` and sum up their values. Then, return the sum divided by the count.
|
|
|
|
## 5. Alternate Averages
|
|
|
|
- Sequence types such as `list` support a few [common operations][common sequence operations].
|
|
- To access an element, use the square brackets (`<list>[]`) notation.
|
|
- Remember that the first element of the `list` is at index 0 from the **left-hand** side.
|
|
- In Python, negative indexing starts at -1 from the **right-hand** side. This means that you can find the last element of a `list` by using `<list>[-1]`.
|
|
- Think about how you could reuse the code from the functions that you have already implemented.
|
|
|
|
## 6. More Averaging Techniques
|
|
|
|
- Sequence types such as `list` already support a few [common operations][common sequence operations].
|
|
- Think about reusing the code from the functions that you just implemented.
|
|
- The slice syntax supports a _step value_ (`<list>[<start>:<stop>:<step>]`).
|
|
|
|
## 7. Bonus Round Rules
|
|
|
|
- Lists are _mutable_. Once a `list` is created, you can modify, delete or add any type of element you wish.
|
|
- Python provides a wide range of [ways to modify `lists`][ways to modify `lists`].
