-The Python SDK provides a generic set of wrappers so you can make API calls easily. It performs some validation before connecting to the API server: for example, it refuses to do an API call if a required parameter is missing.

+{% endcomment %}
 
-The library also includes some conveniences for use in Crunch scripts; see "Crunch utility libraries":crunch-utility-libraries.html for details.
+The Python SDK provides access from Python to the Arvados API and Keep, along with a number of command line tools for using and administering Arvados and Keep.
 
-h3. Installation
+h2. Installation
 
 If you are logged in to an Arvados VM, the Python SDK should be installed.
 
-To use the Python SDK elsewhere, you can install from a distribution package, PyPI, or source.
+To use the Python SDK elsewhere, you can install from PyPI or a distribution package.
 
-{% include 'notebox_begin' %}
-The Python SDK requires Python 2.7.
-{% include 'notebox_end' %}
+The Python SDK supports Python 2.7 and 3.4+
 
-h4. Option 1: Install from distribution packages
+h2. Option 1: Install from a distribution package
 
-First, "add the appropriate package repository for your distribution":{{ site.baseurl }}/install/install-manual-prerequisites.html#repos.
+This installation method is recommended to make the CLI tools available system-wide. It can coexist with the installation method described in option 2, below.
 
-{% include 'note_python27_sc' %}
+First, configure the "Arvados package repositories":../../install/packages.html
 
-On Debian-based systems:
+{% assign arvados_component = 'python-arvados-python-client' %}
 
-<notextile>
-<pre><code>~$ <span class="userinput">sudo apt-get install python-arvados-python-client</code>
-</code></pre>
-</notextile>
+{% include 'install_packages' %}
 
-On Red Hat-based systems:
+h2. Option 2: Install with pip
 
-<notextile>
-<pre><code>~$ <span class="userinput">sudo yum install python27-python-arvados-python-client</code>
-</code></pre>
-</notextile>
+This installation method is recommended to use the SDK in your own Python programs. If installed into a @virtualenv@, it can coexist with the system-wide installation method from a distribution package.
 
-h4. Option 2: Install with pip
+Run @pip install arvados-python-client@ in an appropriate installation environment, such as a @virtualenv@.
 
-Run @pip-2.7 install arvados-python-client@ in an appropriate installation environment, such as a virtualenv.
+Note:
 
-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-2.7 install --pre arvados-python-client@.
+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:
 
-h4. Option 3: Install from source
+<pre>
+$ apt-get install git build-essential python-dev libcurl4-openssl-dev libssl1.0-dev
+</pre>
 
-Install the @python-setuptools@ package from your distribution.  Then run the following:
+For Python 3 this is
 
-<notextile>
-<pre><code>~$ <span class="userinput">git clone https://github.com/curoverse/arvados.git</span>
-~$ <span class="userinput">cd arvados/sdk/python</span>
-~$ <span class="userinput">python2.7 setup.py install</span>
-</code></pre>
-</notextile>
+<pre>
+$ apt-get install git build-essential python3-dev libcurl4-openssl-dev libssl1.0-dev
+</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@.
 
-You may optionally run the final installation command in a virtualenv, or with the @--user@ option.

-<pre><code class="userinput">current_user = arvados.api('v1').users().current().execute()
-</code></pre>

-<pre><code class="userinput">my_uuid = current_user['uuid']

-Create an object:
+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:

-    body={'link_class':'test','name':'test'}).execute()
