This two-part course is designed to help students with very little or no computing background learn the basics of building simple interactive applications. Our language of choice, Python, is an easy-to learn, high-level computer language that is used in many of the computational courses offered on Coursera. To make learning Python easy, we have developed a new browser-based programming environment that makes developing interactive applications in Python simple.

These applications will involve windows whose contents are graphical and respond to buttons, the keyboard and the mouse. In part 2 of this course, we will introduce more elements of programming such as list, dictionaries, and loops and then use these elements to create games such as Blackjack.

Part 1 of this class will culminate in building a version of the classic arcade game "Asteroids". Upon completing this course, you will be able to write small, but interesting Python programs. The next course in the specialization will begin to introduce a more principled approach to writing programs and solving computational problems that will allow you to write larger and more complex programs.

Stephen Wong Lecturer.You write a few lines of code and a few moments later you have something that is happily moving around the screen. In this tutorial, I am going to show you how to take this fun to a whole new level You are going to learn how to animate what you draw yourself as opposed to using something predefined out of a can like a divimgor some other DOM element.

Before you know it, you are going to animate something similar to the following example where you handpicked and carefully placed every pixel in the right location:. Your browser does not support inline frames or is currently configured not to display inline frames. Ok, maybe that was a bit of an exaggeration, but you will animate something that you drew yourself.

This tutorial will show you how and acknowledge the madness behind why you would actually want to do something like this. Animating the things you draw is very different from animating DOM elements. Before we get wrapped up on implementation details, let's talk a little bit about those differences at a high level first. Knowing how to think about this new world will actually make everything easier The canvas element is very simple.

All it does is take your JavaScript instructions on what exactly to draw and turns them into pixels that you can then see. Unfortunately, that's all the canvas element does as well. It isn't a particularly deep element and, for the most part, quite lazy.

As you will see shortly, you'll be doing a lot of extra work to draw and animate on it.

Adding the canvas element to your page is easy. Communicating with it to get some pixels to show up and animate is a challenge - especially if you don't speak its language. The way you draw and animate on a canvas is very similar to how people created animations manually back in the day.

Initially, your canvas is completely blank. Let's call this initial state frame 1 :. You draw everything from the things in the foreground to things that appear in the middle to the things that make up the background.

Every single detail is under your control. It has to be, for it certainly isn't controlled by the canvas. Once you are happy with how the first frame looks like, you clear everything that is shown.

What you have now is a new frame:. In this new frame, which we will affectionately call frame 2you re-draw everything you had in frame 1 but alter the things that you want animated just slightly:. In our example, between frame 1 and frame 2, the pentagon shape rotated slightly and moved over and down a little bit. Everything else is pretty much the same.

Now, if you compare frame 1 and frame 2 side by side, you'll be better able to see the subtle changes:. Now, repeat this draw and clear process over and over again for frame 3, frame 4, frame 5, and so on.This two-part course is designed to help students with very little or no computing background learn the basics of building simple interactive applications.

Refer to the CodeSkulptor documentation. Given two sets, s and twe want a new set containing all the elements that are in one of the sets, but not both of the sets. For example, if s has the elements 1, 2, 3, 4, and t has the elements 3, 4, 5, 6, then the result should have the elements 1, 2, 5, 6.

A set is an unordered collection of distinct elements. Which of the following problem contexts represent instances of this idea? How many frames per second are typically projected in modern movies? How many times per second is the draw handler typically called in CodeSkulptor? Enter two numbers representing these frame rates in frames per second.

Each animated sprite includes an associated tiled image, each of whose sub-images are drawn in turn during the process of animating the sprite. What attribute also known as a field of this Sprite class can be used to select the appropriate sub-image to draw during this animation process?

If you are stuck, review the bonus phase in the mini-project description. Here is the text of the relevant instruction from the bonus phase: "In the draw method of the Sprite class, check if self. If so, then choose the correct tile in the image based on the age. The image is tiled horizontally. If self.

I think that classes simplify you a lot of time plus the code becomes more organized. I am creating a class in order to animate objects with code. The class that I am creating enables you to use the main animations. If I want to animate an object based on that class I would do:. I just finish building this class and I cannot seem to figure out when I am able to animate several things at the same time and when I am not able to. Most of the time I am able to animate two things or more. Let me provide the code for the class I think that with some modifications it can be very helpfull.

Anyways here is the code:. I think that class can save a lot of time and be very useful. Or maybe I have to run the methods in separate threads in order to animate several things at the same time? Why does it not work simultaneously? Simple, if you choose a manipulation as the target property the class will overwrite the existing manipulation that is saved in the target's RenderTransformcompletely disregarding any existing transformsso if you want a translation the manipulation will be changed to that, if you then start a rotation the translation will be gone.

Animation; using System.Matplotlib and Seaborn are some nice libraries in Python to create great looking plots. How nice would it be if in you next presentation, video or social media post you can present development in the data by using a short video clip?

And even better, you can still keep using Matplotlib, Seaborn or any other library that you like to use for your plots! In this post I will be using Matplotlib with the addition of Seaborn for plotting and Numpy together with Pandas for data handling.

For the animation matplotlib offers some functions that we can use. So lets go ahead and import all dependencies. Now to get ready for animating the data we only need to load it and put it into a Pandas DataFrame. When making several plots concerning overdoses on different opioids it can be convenient to also write a function for loading the data from the row you are interested in. So now lets start and get to the animation! One for the year and the other for the count of overdoses. Next we initialize a writer which uses ffmpeg and records at 20 fps with a bitrate of You can of course pick these values yourself.

Now lets create a figure with some labels. The heart piece of your animation is your animation function in which you define what happens in each frame of your video. Here i represents the index of the frame in the animation. With this index you can select the data range which should be visible in this frame. After doing that I use a seaborn lineplot to plot this data selection. The last two lines are just to make the plot look a bit more pleasing.

To start the animation use matplotlib. FuncAnimation in which you link the animation function and define how many frames your animation should contain.

To save this animation as an mp4 you can simply call ani. If you just want to take a look at it before you save it call plt. So now the animation looks like this:.

It kind of works but it is still very jumpy. To avoid the jumpiness of it we need some more data points in between the ones we already have. For this we can use another function which I call here augment. Now we just need to apply this function to our data and increase the number of frames in the matplotlib.

FuncAnimation function. The result looks much more smooth but there are still some sharp edges where the data values change. Additionally we can add some color and style parameter to make the plot look more individual.

This is how we obtain the final result shown above. This post just shows the matplotlib animation function on one example.

Of course you can use it for any kind of plot you want to animate. Simple adjust the parameters and plot type inside your animate function and the possibilities are endless. Sign in. How to Create Animated Graphs in Python.
