To use the Python SDK elsewhere, you can install from PyPI or a distribution package.
-As of Arvados 2.1, the Python SDK requires Python 3.5+. The last version to support Python 2.7 is Arvados 2.0.4.
+As of Arvados 2.2, the Python SDK requires Python 3.6+. The last version to support Python 2.7 is Arvados 2.0.4.
h2. Option 1: Install from a distribution package
Note:
-The SDK uses @pycurl@ which depends on the @libcurl@ C library. To build the module you may have to first install additional packages. On Debian 9 this is:

<pre>

If your version of @pip@ is 1.4 or newer, the @pip install@ command might give an error: "Could not find a version that satisfies the requirement arvados-python-client". If this happens, try @pip install --pre arvados-python-client@.
If you installed from a distribution package (option 2): the package includes a virtualenv, which means the correct Python environment needs to be loaded before the Arvados SDK can be imported. This can be done by activating the virtualenv first:
+{% include 'notebox_begin_warning' %}
+If you are on Ubuntu 18.04, please note that the Arvados packages that use Python depend on the python-3.8 package. This means they are installed under @/usr/share/python3.8@, not @/usr/share/python3@. You will need to update the commands below accordingly.
+{% include 'notebox_end' %}
+
<notextile>
-<pre>~$ <code class="userinput">source /usr/share/python2.7/dist/python-arvados-python-client/bin/activate</code>
+<pre>~$ <code class="userinput">source /usr/share/python3/dist/python3-arvados-python-client/bin/activate</code>

Python 3.7.3 (default, Jul 25 2020, 13:03:44)

Or alternatively, by using the Python executable from the virtualenv directly:
<notextile>
-<pre>~$ <code class="userinput">/usr/share/python2.7/dist/python-arvados-python-client/bin/python</code>
+<pre>~$ <code class="userinput">/usr/share/python3/dist/python3-arvados-python-client/bin/python</code>

-h3. Notes
-
-The general form of an API call is:
-
-<notextile>
-<pre><code class="userinput">arvados.api(<i>api_version</i>).<i>plural_resource_type</i>().<i>api_method</i>(<i>parameter</i>=<i>value</i>, ...).execute()
-</code></pre>
-</notextile>
-
-Many API methods accept a parameter whose name is the same as the resource type. For example, @links.create@ accepts a parameter called @link@. This parameter should be given as @body@.
-
-<notextile>
-<pre><code class="userinput">arvados.api('v1').links().create(
- uuid=test_link['uuid'],
- body={'properties':{'foo':'bar'}}).execute()
-</code></pre>
-</notextile>
-
-One way to make API calls slightly less verbose is:
-
-<notextile>
-<pre><code class="userinput">arv = arvados.api('v1')
-j = arv.jobs().list().execute()
-</code></pre>
-</notextile>
-
-The SDK retrieves the list of API methods from the server at run time. Therefore, the set of available methods is determined by the server version rather than the SDK version.
