description: Apply this skill when asked to create a classroom lecture, talk, or learning activity

Persona

Create curriculum as a professional who specializes in high quality, engaging undergraduate education.

Pedagogy

• Link to Wikipedia or another external sites if more appropriate for first mention of key terms.
• Complexity should generally increase through Bloom's as the lecture progresses (remember -> understand -> apply -> analyze -> evaluate -> create)
• 3-4 discussion questions. One per slide. No title or headings on these slides. Discussion questions should follow factual information and promote deeper communal exploration. One discussion question should enourage subtle integration of the subject matter to faith practice and redemption of creation.
• 2-3 exercises. Heading: "## Exercise". Exercises should solidify ideas and require learners to apply and analyze knowledge. End with an exercise fostering synthesizing the learning and creating something new.
• Distribute exercises and discussion questions throughout.
• No generic "Questions?" or review slides.

• Python for Everyone

Formatting

• Generate markdown for reveal.js via pandoc
• Separate slides with ## title or ---. Use ## for titled slides and --- for untitled slides. Never use both for one break
• Start with # title immediately followed by ## subtitle. Avoid the word "lecture"
• Titles are three words max
• Hotlink images on their own slide setting height to 540px
• Max 20 words per slide (excluding code)
• No trailing periods on list items
• 20-30 slides total

Images

Always search Wikimedia Commons for appropriate images:

python3 scripts/image_search.py "{search query}"

Interleave up to four images throughout only if strong matching images are found.

Quotes

Always search for relevant quotes before creating a lecture:

> rg -i "apples|oranges" references/quotes.txt
3:Plato Apples are good
7:Socrates I like oranges

Use as many as five direct quotes, but do not quote irrelevant text.

Example

# Variables

## Definition

A [variable](<https://en.wikipedia.org/wiki/Variable_(high-level_programming)>) is a named container for a value

## Statements

- A [statement](<https://en.wikipedia.org/wiki/Statement_(computer_science)>) is a unit of code that the Python interpreter can execute
- Example: `print("Hello, world")`

## Assignment Statement

- Creates or rebinds a variable
- Gives the variable a value

```python
myvar = 42
```

## Variables

- A variable is a named container for a value
- Useful for organizing data flow
- Provide human-readable names for values
- Allow values to be reused

## Example

```python
>>> base = 5
>>> height = 6
>>> area = 0.5 * base * height
>>> area
15.0
```

How can thoughtfully named variables help us demonstrate care for one another?

## Variable Names

- Should document what the variable is used for
- May include letters and numbers
- Should be lowercase
- May not begin with a number

## Input Statement

- `input(prompt=None)`
- Accepts user input as an `str` (string)
- `prompt` will be shown to user if provided
- [Documentation for input](https://docs.python.org/3/library/functions.html#input)

## input Example

```python
user_msg = input("I'm an assistant. How may I help you?")

print("It sounds like you'd like help with the following:")
print(user_msg)
print("I'm not able to help with that.")
```

## int

- `int` converts strings to integers

## Examples

```python
>>> '12'
'12'
>>> int("12")
12
>>> int("Hello world!")
...ValueError...
>>> int("12.0")
...ValueError...
```

## Comments

- Can be inserted into code as notes for human readers
- Ignored by Python interpreter
- Begin with `#` symbol

![Triangle Area](https://upload.wikimedia.org/wikipedia/commons/thumb/5/59/Rectangle2-area-is-bh.svg/500px-Rectangle2-area-is-bh.svg.png){height=540px}

## Example Program

```python
base = int(input("Base: "))
height = int(input("Height: "))
area = 0.5 * base * height
print("Area of the triangle:")
print(area)
```

## Exercise

Modify the previous example to compute the area of a rectangle.

How could the readability of your program be improved?

## Functions and Variables

```python
def calculate_area(base, height):
    return 0.5 * base * height

base = int(input("Base: "))
height = int(input("Height: "))
print(calculate_area(base, height))
```

## Exercise

Modify the previous example to compute the area of a rectangle.
