Reveal.js

+

The HTML Presentation Framework

+

+ Created by Hakim El Hattab and contributors +

+
+ +
+

Hello There

+

+ reveal.js enables you to create beautiful interactive slide decks using HTML. This presentation will show you examples of what it can do. +

+
+ + +
+
+

Vertical Slides

+

Slides can be nested inside of each other.

+

Use the Space key to navigate through all slides.

+
+ + Down arrow + +
+
+

Basement Level 1

+

Nested slides are useful for adding additional detail underneath a high level horizontal slide.

+
+
+

Basement Level 2

+

That's it, time to go back up.

+
+ + Up arrow + +
+
+ +
+

Slides

+

+ Not a coder? Not a problem. There's a fully-featured visual editor for authoring these, try it out at https://slides.com. +

+
+ +
+

Point of View

+

+ Press ESC to enter the slide overview. +

+

+ Hold down the alt key (ctrl in Linux) and click on any element to zoom towards it using zoom.js. Click again to zoom back out. +

+

+ (NOTE: Use ctrl + click in Linux.) +

+
+ +
+

Touch Optimized

+

+ Presentations look great on touch devices, like mobile phones and tablets. Simply swipe through your slides. +

+
+ +
+ +
+ +
+
+

Fragments

+

Hit the next arrow...

+

... to step through ...

+

... a fragmented slide.

+ + +
+
+

Fragment Styles

+

There's different types of fragments, like:

+

grow

+

shrink

+

fade-out

+

+ fade-right, + up, + down, + left +

+

fade-in-then-out

+

fade-in-then-semi-out

+

Highlight red blue green

+
+
+ +
+

Transition Styles

+

+ You can select from different transitions, like:
+ None - + Fade - + Slide - + Convex - + Concave - + Zoom +

+
+ +
+

Themes

+

+ reveal.js comes with a few themes built in:
+ + Black (default) - + White - + League - + Sky - + Beige - + Simple
+ Serif - + Blood - + Night - + Moon - + Solarized +

+
+ +
+
+

Slide Backgrounds

+

+ Set data-background="#dddddd" on a slide to change the background color. All CSS color formats are supported. +

+ + Down arrow + +
+
+

Image Backgrounds

+ 
<section data-background="image.png">
+
+
+

Tiled Backgrounds

+ 
<section data-background="image.png" data-background-repeat="repeat" data-background-size="100px">
+
+
+
+

Video Backgrounds

+ 
<section data-background-video="video.mp4,video.webm">
+
+
+
+

... and GIFs!

+
+
+ +
+

Background Transitions

+

+ Different background transitions are available via the backgroundTransition option. This one's called "zoom". +

+ 
Reveal.configure({ backgroundTransition: 'zoom' })
+
+ +
+

Background Transitions

+

+ You can override background transitions per-slide. +

+ 
<section data-background-transition="zoom">
+
+ +
+
+

Iframe Backgrounds

+

Since reveal.js runs on the web, you can easily embed other web content. Try interacting with the page in the background.

+
+
+ +
+

Pretty Code

+ 

+import React, { useState } from 'react';
+
+function Example() {
+  const [count, setCount] = useState(0);
+
+  return (
+    <div>
+      <p>You clicked {count} times</p>
+      <button onClick={() => setCount(count + 1)}>
+        Click me
+      </button>
+    </div>
+  );
+}
+
+

Clever Quotes

+

+ These guys come in two forms, inline: The nice thing about standards is that there are so many to choose from and block: +

+
+ “For years there has been a theory that millions of monkeys typing at random on millions of typewriters would + reproduce the entire works of Shakespeare. The Internet has proven this theory to be untrue.” +
+
+ +
+

Intergalactic Interconnections

+

+ You can link between slides internally, + like this. +

+
+ +
+

Speaker View

+

There's a speaker view. It includes a timer, preview of the upcoming slide as well as your speaker notes.

+

Press the S key to try it out.

+ + +
+ +
+

Export to PDF

+

Presentations can be exported to PDF, here's an example:

+ +
+ +
+

Global State

+

+ Set data-state="something" on a slide and "something" + will be added as a class to the document element when the slide is open. This lets you + apply broader style changes, like switching the page background. +

+
+ +
+

State Events

+

+ Additionally custom events can be triggered on a per slide basis by binding to the data-state name. +

+ 

+Reveal.addEventListener( 'customevent', function() {
+	console.log( '"customevent" has fired' );
+} );
+
+
+ +
+

Take a Moment

+

+ Press B or . on your keyboard to pause the presentation. This is helpful when you're on stage and want to take distracting slides off the screen. +

+

Why Python?

+
+
+
    +
  • Easy to learn
    • +
  • Concise and elegant
    • +
  • Multiple paradigms (OOP, functional)
    • +
  • Interpreted, multiplatform, free software
    • +
  • Relatively slow per se, but you can move the heavier work to libraries that use low level implementations behind the scene. Will see some of this soon.
    • +
  • The most common language for data science, huge collection of + libraries and tools available, growing fast
    • +
  • Vibrant community, worldwide and in Berlin
    • +
+
+
+

Install Python

+
    +
  • Recommended: Anaconda +
      +
    • For new users who want a full Python environment for Data Science
      • +
    • Free and open source, download from continuum.io
      • +
    +
    • +
  • Manual installation: +
      +
    • (Only) if you already have been using Python for some time
      • +
    • pip install -U numpy, scipy, ipython, matplotlib, pandas, scikit-learn
      • +
    • Use virtualenvs to make easier to track dependencies
      • +
    +
    • +
+
+
+

Use Python

+

Two (three) ways

+
    +
  1. REPL (Read Evaluate print Loop), interactive
    2. +
  2. Create python (.py) files and pass them to the interpreter
    3. +
  3. Just use an IDE and let it invoke the interpreter for you
    4. +
+
+
+
+
IPython
+
Interactive Python shell and Jupyter, a web-based notebook. Integrate Python code with formatted text, charts and more
+
Numpy + SciPy
+
Provides powerful numerical array objects, and routines to manipulate them. Heavily used by the other packages
+
Matplotlib
+
2- and 3-D visualisations and plots​
+
Scikit-learn
+
Machine Learning toolbox
+
Pandas
+
Tools for explorative analysis
+
Tensorflow, Keras, Pytorch
+
(deep) neural networks
+
+
+
+

Python 2 and Python 3

+

The way Python 2 (2000) manages text, in particular non-English characters, originates problems which could be fixed only by breaking compatibility and releasing Python 3 (2008).

+

Many features were added to Python 3 over different versions, the latest is 3.7 (June 2018).

+

Python 2 does not receive new functionalities since 2010 and will not be officially supported after January 1st, 2020

+
+
+

Use Python 3

+

(Unless you really really really need a library that works only on Python 2)

+
+
+

Python 3.6 and later: f-strings

+ 

+                    >>> print(f'The result of 3+2 is {3 + 2} and 1/3 is {1/3 :.3f}')
+                    The result of 3+2 is 5 and 1/3 is 0.333
+
+

Also good to know: type hinting, async

+ 

+                    def repeat(a: int, b:str) -> str:
+                        return b * a
+
+
+
+

List comprehension

+ 

+                        [x*10 for x in range(1, 200) if x%2 == 0]
+
+

Similar for sets and dictionaries

+ 

+                        {x % 10 for x in range(200)}
+                        {x:x%10 for x in range(19)}
+
+
+
+

Exercise

+

Calculate the sum of all the squares between 1 and 1 million.

+

Remember: Python has a built-in function sum to sum all the elements of a sequence.

+
+
+

Keyword only arguments

+

You can create functions which accept optional arguments

+ 

+                    def myfun(a, b, name='John'):
+                        print(f'a * b = {a * b}')
+                        print('your name is {name}')
+                    def anotherfun(a, b, *c):
+                        print(f'you passed {len(c)} extra arguments')
+
+
+
+

Exercise: variable number of arguments

+

Write a function called mysum that accepts an arbitrary number of arguments and sum them.

+ 

+                        >>> mysum()
+                        0
+                        >>> mysum(42)
+                        42
+                        >>> mysum(1, 23, 134, .8, 0xB)
+                        169.8
+
+
+
+

Exercise: what will this print?

+ 

+                        a = [1, 3]
+                        b = a
+                        a[1] = 42
+                        print(a)
+                        print(b)
+
+
+
+

Exercise: what will this print?

+ 

+                    def tricky(a=[]):
+                        a.append(1)
+                        print(a)
+
+                    tricky()
+                    tricky([23])
+                    tricky()
+                    tricky([0])
+
+

Avoid using mutable objects as default arguments. + Numbers, strings, booleans, tuples and None are OK. +

+
+
+

Iterators

+

In Python you can iterate over many types of values

+ 

+                    for l in "atlantic":
+                        print(l)
+
+                    for line in open('data.txt', 'r'):
+                        print(line)
+
+                    for idx, line in enumerate(open('data.txt', 'r')):
+                        print(idx, line)
+
+                    print(sum(range(10000))) # it's an iterator, is not "materialized"
+
+
+
+

Mutable vs. Immutable

+

Immutable data can help you. Avoid creating functions which change the argument, unless it's obviously their goal.

+

You can't use mutable values as dictionary keys:

+ 

+                        {
+                            [1,2]: "hello", # this doesn't work
+                            (2,56): [91, 78, ["cat"]] # this is OK
+                        }
+
+
+
+

Exercise: frequency count

+

Create a function that given a string return the two most frequent characters.

+

Extra: can you do that with most frequent words instead?

+
+
+

Slicing

+ 

+                        l = [12, 13, 14, 15, 900]
+                        >> l[1:4]
+                        [13, 14, 15]
+                        >> l[:2]
+                        [12, 13]
+                        >>l[0:900:2]
+                        [12, 14, 900]
+                        >> l[0:1000:2]
+                        [12, 14, 900]
+                        >> l[-1:-3]
+                        []
+                        >>l[-3:-1]
+                        [14, 15]
+
+
+
+

Generators

+

Python3 tries to be as lazy as possible: it calculates values only when needed, saving memory and time. This can be critical to process big datasets.

+

sum(range(1_000_000_000)) does not need to create that many values.

+

You can create a function that gives value only when necessary using yield instead of return. It give the value back to the caller, but unlike return it preserve the state of the function which can yield again and again.

+

Note: when it's simple you can use () instead of [] like with list comprehension.

+
+
+

Exercise: recursion

+

Create a function that returns the N-th Fibonacci number using recursion.

+

Hint: Fibonacci number X is just the sum of the two fibonacci numbers at positions X-1 and X-2. The first two Fibonacci numbers are 1

+

Try it with small numbers, then 40, how long does it take?

+
+
+

lru_cache

+ 

+                        from functools import lru_cache
+                        @lru_cache()
+                        def fibo(n):
+                            if n in [1, 2]:
+                                return 1
+                            else:
+                                return fibo(n-1) + fibo (n-2)
+                        print(fibo(40))
+
+
+
+
+

Closures

+

In python everything is an object, including functions.

+

When you define a function, it captures values defines outside it. This is called closure.

+

Exercise: define a function called "adder" which returns a function which add a given value

+ + 

+                        >>> my_adder = adder(5)
+                        my_adder(100)
+                        105
+
+
+
+

Decorators

+

If you write @function_name before defining a function, python will pass it to function_name and replace the original function with its output

+

Seems complicated, but an example can help a lot.

+

Example: a function that prints the value passed to the wrapped one before and after

+

Exercise: create a decorator which checks that a function was called with a positive number, if not does not invoke it but prints an error instead

+
+
+

Classes

+

OOP is a huge topic, let's review the basis.

+

A class defines how its instances behave. "Mars" is an instance, "Planet" is a class.

+

Classes can inherit from each other, for example if "GasPlanet" inherits from "Planet", it has all its characteristics plus more. "Saturn" is an instance of "GasPlanet".

+

Official documentation here, but is pretty dense. We'll see an example.

+
+
+

Some words on coding style

+

Don't spend too much time on aesthetic and nitpicking, but being consistent is useful:

+
    +
  1. Makes easier to re-read your own code
    2. +
  2. It helps others read your code
    3. +
  3. Gives a better impression when the code is published
    4. +
+

Python has an official style guide called PEP8, there are tools for all IDEs to check it as you type, on the long run they help make it an habit.

+

If you work on an existing codebase with others, stick with the existing conventions and naming.

+
+
+

Naming

+

Use meaningful names. No asdasd

+

UPPERCASE for module constants that are never changed

+

CamelCase for classes

+

lowercase_with_underscore for everything else (variables and functions)

+
+
+

Docstrings

+

You can document a function like this:

+ 

+                def myfun(a, b):
+                    """What this function does.
+                    Some description for humans.
+                    """
+                    return a * b
+
+

This is the text shown by editors when you type, use it when especially the function is not obvious.

+

There are two mainstream standards, numpy and google, about how to format the text. Use whatever the codebase is using, or your taste.

+
+
+

Tests

+

When your code becomes more complex, it's a very good idea to include automated tests.

+
    +
  • It saves time with regressions
    • +
  • Makes collaborations easier and safer
    • +
  • It's part of a CI/CD pipeline
    • +
  • Gives the project a more professional look when published
    + Tip: once you have tests, it's trivial to add a CI badge to the README page
    • +
+

You probably want pytest, but the specific library is not as important as is having tests in first place.

+
