+# Command-line arguments
+
+!!!- info "Learning objectives"
+
+    - Can read the command-line arguments
+    - Can run a Python script with command-line arguments
+
+???- question "For teachers"
+
+    Teaching goals are:
+
+    * Learners have used sys.args
+    * Learners have run a Python script with command-line arguments
+
+    Lesson plan:
+
+    * 5 mins: prior knowledge
+    * 5 mins: presentation
+    * 15 mins: challenge
+    * 5 mins: feedback
+
+## Overview
+
+Sometime, also programs need input, for example
+the name of the input file and the name of a results file:
+
+```
+python3 my_input.csv my_results.csv
+```
+
+Sometime you need to get 'stuff to work', for example,
+code written by someone else. 
+In this session, we practice this, 
+going through the problems and errors that occur 
+when you want to 'just want to run the stupid code'.
+
+## 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
+    - Practice to search for an UPPMAX module that needs to be loaded
+    - Get a script that requires an UPPMAX module to be loaded to work
+
+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.
+
+???- question "Need more hints?"
+
+    The exercise is about *practicing* to search for an UPPMAX module,
+    hence giving away the answer makes this session useless.
+
+    However, if you feel stuck too much, 
+    you can watch a video in which this exercise is done
+    [here](https://youtu.be/bnN-1uzsgvk)
