PROGRAMS FOR USING PYTHON ON MAC INSTALL
If you are running Windows you will likely have to install Python yourself. Python 2 "/' 3 will highlight the differences when they are first encountered in the text. Example programs in this text are written using Python 3 syntax but the differences between Python 2 and 3 are few enough that it is possible to use either Python 2 or 3 when writing programs for the exercises in this text. If you are using this book as part of an introductory course, your instructor may prefer you install one version or the other. There were some significant changes between Python 2.7 and Python 3 which included a few changes that make programs written for version 3 incompatible with programs written for version 2.7 and vice versa. Because the Binder servers are shared among a large number of people, performance can vary a great deal from day to day and from hour to hour.To begin writing Python programs on your own computer, you need to have Python installed. Here is an explanation of the Binder mechanism. There is a Binder package of some demo programs, which lets you run Jupyter VPython programs even on computers or mobile devices that do not have Python installed.

There is a suite of demo programs for use with a Jupyter notebook or JupyterLab ( zip file). Moreover, you can re-run the program more easily. It also ensures that the vpython module has been fully initialized before continuing.
The result is that the 3D display will be shown just under the first cell instead of at the end of the last cell. Then put the rest of the program in later cells. Some users find it convenient to include in the first cell just these statements: Currently, to re-run a VPython program you need to click the circular arrow icon to "restart the kernel" and then click the red-highlighted button, then click in the first cell, then click the run icon.
This simplifies moving programs between GlowScript VPython and VPython 7.Ĭlick in the first cell (containing the vpython import statement), then click the run icon, the one that is a rightward-facing triangle touching a vertical line.

If you have a recent release of the Mac operating system, to start the Jupyter notebook you may need to execute this:Įither with or without a Jupyter notebook or lab, "from vpython import *" also imports all math functions, clock(), random(), and arange(). Or (depending on what operating system you're using), doubleclick the icon "Jupyter Notebook" or "JupyterLab" that is shown as one of the Anaconda-related tools. In a terminal, execute "jupyter notebook" or "jupyter lab". There are two ways to start a Jupyter notebook or lab. Using the vpython module in a Jupyter notebook or Jupyter lab The following workaround, making and invoking a new environment, does work: "conda create -n vpclean -c vpython vpython python=3" followed by "source activate vpclean". Some Mac users have reported that running from Spyder doesn't work. In Spyder you must go to Tools > Preferences > Run and specify "Execute in a dedicated Python console". You can start Spyder by clicking the Spyder icon that is installed with Anaconda, or you can start Spyder from a command prompt by typing "spyder". For older versions of VPython, a simple option is to install the older Spyder 3.1.4 by executing "conda install spyder=3.1.4", though Spyder 3.1.4 doesn't work with Python 3.7, which is what Anaconda now installs.
The newest Spyder requires using VPython 7.5.0 or later. There is a suite of demo programs for use without a Jupyter notebook ( zip file).

In VPython 7.5.0 and later, the following code can be used to shut down a running program:įrom vpython.no_notebook import stop_server You can scroll to see other parts of the display, but you may wish to right-click anywhere in the notebook and select "Disable Scrolling for Outputs," in which case VPython displays normally. In JupyterLab the default is for output to be displayed in a cell that has a very small height, and this includes a VPython display. This simplifies moving programs between Web VPython and VPython 7. This short program will display a white box on a black background:Įither with or without a Jupyter notebook, "from vpython import *" also imports all math functions, clock(), random(), and arange(). You can launch a VPython program from applications such as IDLE, Spyder, or a terminal.
