+## Overview
+
+
+## Exercises
+
+### Exercise 1: Fail at running a first program
+
+!!!- info "Learning objectives"
+
+    - Rehearse creating a script
+    - Try to import a Python package
+    - Observe errors when a package is absent
+
+Read the following sections of [How to Think Like a Computer Scientist: Learning with Python 3](https://openbookproject.net/thinkcs/python/english3e/index.html):
+
+ * 3.1. Our first turtle program
+
+Copy-paste the first script in that section to a script.
+
+Run the script and verify it will not run. Does the error message make sense?
+
+### Exercise 2: Running a first program
+
+!!!- info "Learning objectives"
+
+    - Import a Python package
+    - Search for an UPPMAX module that needs to be loaded
+    - Run a script that requires an UPPMAX module to be loaded
+
+Now we try to make this script work!
+
+Read: 
+
+- [the UPPMAX documentation 'Loading Python packages'](http://docs.uppmax.uu.se/software/python/#loading-python-packages)
+- [the UPPMAX documentation 'Modules'](http://docs.uppmax.uu.se/cluster_guides/modules/)
+
+Now, try to get the script to work. 
+
+When running the code, there should be a visible pop-up window. If not, 
+re-read [the UPPMAX documentation page 'Login to Rackham'](http://docs.uppmax.uu.se/getting_started/login_rackham/)
+and enable X-forwarding.
