Using VPython with installed Python

We recommend installing the Anaconda Python distribution with Python version 3.5.3 or later.
The 3D animations use WebGL in a browser, which is not supported by Internet Explorer.
All current browsers do support WebGL. See webglreport.com to check this.
The vpython module ('VPython 7') is available using
'conda install -c vpython vpython' or 'pip install vpython'.

To update to later versions of vpython use
'conda update -c vpython vpython' or 'pip install vpython --upgrade'.

Python-abp contains a script called fldiff that will find the diff between the latest filter list, and any number of previous filter lists: $ fldiff -o diffs/easylist/ easylist.txt archive/. where -o diffs/easylist/ is the (optional) output directory where the diffs should be written, easylist.txt is the most recent version of the filter list. The “prefix scheme” is useful when you wish to use one Python installation to perform the build/install (i.e., to run the setup script), but install modules into the third-party module directory of a different Python installation (or something that looks like a different Python installation).

Using the vpython module outside a Jupyter notebook (Python 3.5.3 or later)

Read more You can launch a VPython program from applications such as IDLE, Spyder, or a terminal if the version of Python is 3.5.3 or greater.

This short program will display a white box on a black background:
from vpython import *
box()

Either with or without a Jupyter notebook, 'from vpython import *' also imports all math functions, clock(), random(), and arange(). This simplifies moving programs between GlowScript VPython and VPython 7.

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. 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 VPython 7.5.0 and later, the following code can be used to shut down a running program:

from vpython.no_notebook import stop_server
stop_server()

There is a suite of demo programs for use without a Jupyter notebook (zip file).

The newest Spyder requires using VPython 7.5.0 or later. 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. 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'. In Spyder you must go to Tools > Preferences > Run and specify 'Execute in a dedicated Python console'.

Some Mac users have reported that running from Spyder doesn't work. 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'.

Using the vpython module in a Jupyter notebook or Jupyter lab (Python 3.5.3 or greater)

Read more

If you use Jupyter lab, after installing VPython you need to install Node.js (https://nodejs.org/en/download/) and then execute this:

jupyter labextension install vpython

There are two ways to start a Jupyter notebook or lab. In a terminal, execute 'jupyter notebook' or 'jupyter lab'. 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.

If you have a recent release of the Mac operating system, to start the Jupyter notebook you may need to execute this:
jupyter notebook --browser=Chrome

This short program will display a white box on a black background:
from vpython import *
box()

Either with or without a Jupyter notebook or lab, 'from vpython import *' also imports all math functions, clock(), random(), and arange(). This simplifies moving programs between GlowScript VPython and VPython 7.

Click 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. 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. Some users find it convenient to include in the first cell just these statements:

from vpython import*
scene = canvas()

Then put the rest of the program in later cells. The result is that the 3D display will be shown just under the first cell instead of at the end of the last cell. It also ensures that the vpython module has been fully initialized before continuing. Moreover, you can re-run the program more easily.

There is a suite of demo programs for use with a Jupyter notebook or JupyterLab (zip file).

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. Here is an explanation of the Binder mechanism. 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.

VPython 6, which is no longer supported

Read more

Here is documentation on the older VPython 6 (the 'visual' module), which as of January 2016 is still available but no longer supported. The main differences are that vectors must now be represented as vector(x,y,z) or vec(x,y,z), not as (x,y,z), the name 'display' has been changed to 'canvas', the name 'gdisplay' has been changed to 'graph', and the curve and points objects have a new set of methods. This Python program does an imperfect but useful job of converting old programs to the new syntax.

Latest version

Released:

A small Python module for determining appropriate platform-specific dirs, e.g. Getting authorization code for omnisphere 2. a 'user data dir'.

Project description

the problem

What directory should your app use for storing user data? If running on Mac OS X, youshould use:

If on Windows (at least English Win XP) that should be:

or possibly:

for roaming profiles but that is another story.

On Linux (and other Unices) the dir, according to the XDGspec, is:

`appdirs` to the rescue

This kind of thing is what the appdirs module is for. appdirs willhelp you choose an appropriate:

user data dir (user_data_dir)
user config dir (user_config_dir)
user cache dir (user_cache_dir)
site data dir (site_data_dir)
site config dir (site_config_dir)
user log dir (user_log_dir)

and also:

is a single module so other Python packages can include their own private copy
is slightly opinionated on the directory names used. Look for “OPINION” indocumentation and code for when an opinion is being applied.
