# Overview
|
|
|
This lesson starts with a recap of all of the topics covered up to this point, giving students a final chance to express their questions before we move beyond the basics. Most slides are in a "Lecture + Question -> Answer" format. It then has a very quick overview of the upcoming unit — user input and file I/O, abstraction, modules, and APIs.
|
|
|
|
|
|
- As you go through this lesson, do frequent checks for understanding. It's important that students understand everything before we add more complicated things like `itertools` and APIs.
|
|
|
|
|
|
- When you get to the new unit overview, put questions in the parking lot — there's a presentation on each topic.
|
|
|
|
|
|
# Differentiation and Extensions
|
|
|
|
|
|
- If students are breezing through this lesson, that's great! Don't stop for long on each slide.
|
|
|
- If students are having trouble in the recap, add in We Dos.
|
|
|
|
|
|
# Learning Objectives
|
|
|
In this lesson, students will:
|
|
|
|
|
|
- Confidently recap the previous units.
|
|

**Talking Points:**
|
|
|
|
|
|
- This lesson is pretty solidly a review.
|
|
|
- Then, we'll very briefly introduce all of the concepts covered the next unit. Don't worry about learning them here! It's the final Python unit and it covers quite a lot, so we'll just give you an overview in advance.

**Talking Points:**
|
|
|
|
|
|
- Lists are a collection of items stored in a single variable.
|
|
|
- Lists can be of any type, but they are typically of related items.

**Talking Points:**
|
|
|
|
|
|
- Dictionaries are made of key-value pairs.
|
|
|
- We split lines for readability.

**Teaching Tips:**
|
|
|
|
|
|
- This is long; encourage students to open it in a new window.
|
|
|
- Review the answer afterward.
|
|
|
|
|
|
**Talking Point:**
|
|
|
|
|
|
- Parameters to functions allow us to pass in arguments to use within the function. This is useful when you have very similar code.
|
|
|
|
|
|
**Repl.it note:** The code here is:
|
|
|
```python
|
|
|
# Function definitions:
|
|
|
def say_hello_ada():
|
|
|
print("hello, Ada")
|
|
|
|
|
|
def say_hello_alan():
|
|
|
print("hello, Alan")
|
|
|
|
|
|
def say_hello_linus():
|
|
|
print("hello, Linus")
|
|
|
|
|
|
# Call the functions:
|
|
|
say_hello_ada()
|
|
|
say_hello_alan()
|
|
|
say_hello_linus()
|
|
|
```
|
|
|
|
|
|
> **Challenge:** Could we do this with a single function that has a parameter called "name"?

- Return statements bring data out of a function. They are not the same thing as `print` statements, which simply output text.

**Talking Point:**

**Talking Point:**

- Inheritance is all about reusing code. You may have two classes that are related. Inheritance allows you to take advantage of that.

# Knowledge Check

|
|

We're about to move on to the next unit: Intermediate Python.
|
|
|
|
|
|
Any questions?

# Switching Gears: Preview
|
|
|
|
|
|
The next unit covers many topics, including:
|
|
|
|
|
|
- File I/O
|
|
|
- Modules and libraries
|
|
|
|
|
|
You don't need to memorize them now! This is just an overview.

# User Input and File I/O
|
|
|
|
|
|
You've seen this a few times already with `input()`.
|
|
|
|
|
|
We'll build real interactions between your Python programs and other files — or the person using your app!

# Modules and Libraries
|
|
|
|
|
|
|
|
|
We mentioned these in the pre-work!
|
|
|
|
|
|
Modules and libraries are:
|
|
|
|
|
|
- Code that others have written.
|
|
|
- Free to use!
|
|
|
- Useful extensions of the Python language (e.g., a fancy date and time formatter).

* Lists, sets, tuples, and dictionaries.
|
|
|
* Loops and iteration.
