Tinkering with scripts is a great learning approach even if you only understand part of what's going on in the scripts, you can have fun changing them and seeing what the result is. You can also change them by editing them, saving them, and running them (IDLE will only run a script that has been saved to disk).

Now, feel free to open and run any of the scripts in the examples folder (e.g.

This plot uses data from the NASA GISS website. (You might need to wait for a minute or more before anything happens.) This should produce a plot of global mean temperature at the Earth's surface, as a function of year for several decades (see screenshot below). In the examples folder, find the file called 'matplotlib_example.py', which might show up as matplotlib_example or matplotlib_example.py. We are now ready to move onto the next example. On Mac systems you might have to hold the left and right buttons, or push the option key, and move the mouse.

To zoom and pan, typically you hold down the middle button and move the mouse.

On Mac systems you might have to press the command key and move the mouse.

To rotate the camera, typically you hold down the right mouse button and move the mouse.

The mouse controls on Windows and Mac systems can be different. You can rotate the camera to different orientations or you can zoom and pan. You are looking at the scene from the perspective of a virtual camera you can move the camera around the scene with your mouse. (The shortcut for this is F5.) This should produce an animation of a bouncing ball (see below). Open the file called 'bounce', which might show up as bounce or as bounce.py in the directory listing.

In the IDLE program, using File в†’ Open in Windows or Mac OS, go to the examples folder.

Download the examples folder, unzip it, and look at the list of examples in the folder.

The scripts can be found in the examples folder, which you can download hereas a zip file.

We will try a couple of scripts to get you familiar with how to run them.

There are other ways of running Python, but these are beyond the scope of our current documentation. If you are running MacOS, from the Applications folder, open IDLE as follows:ДЄpplications в†’ Python 2.7 в†’ IDLE will open a 'Python Shell' which will look like the following: The typical result will be a window labelled 'Python Shell' which w ill look like the following: Start в†’ All Programs в†’ Python 2.7 в†’ IDLE (Python GUI)

If you are running Windows, you will be starting IDLE from the Python XY package.

This is because the behaviour you get can be unexpected, although it won't do any harm. Instead, open the scripts from within your IDLE session, using File в†’ Open. py files directly: We do not recommend opening python files ending with. These scripts are also used in the Installing Python documentation. In these activities, we will start an IDLE session and run a couple of simple scripts.

Activities and exercises for you to try are labelled in blue font as Activity 1, Activity 2, etc.Дuring a typical IDLE session, you will try Python commands interactively, and edit and run Python programs.

If you don't understand the color highlighting, don't worry about it for now.

Code written in these boxes includes colored highlighting for different parts of the Python language (commands, variables, comments, etc.).

Blocks of code are shaded in grey boxes like this:.

Python commands and output statements are often set in bold, as in print 'Hello World!'.

We use a few formatting conventions to guide you. If this is not the case, go to the Python installation pages and come back to this tutorial once you've installed the packages. We are assuming that the Python package you will be using for your courses has been installed on your computer.

We will be running Python using IDLE (the ' Integrated Deve Lopment Environment' for Python), which is a software package that lets you test Python commands and edit and run your Python programs. Python is a general-purpose programming language that we will use to teach you the use of computers in physics. Contact: Paul Kushner, tutorial will take you through the basics of using Python with IDLE.
