++This is an org-mode document with code examples in Python. Once opened in +Emacs, this document can easily be exported to HTML, PDF, and Office +formats. For more information on org-mode, see +https://orgmode.org/guide/. +
+ +
+When you type the shortcut C-c C-e h o, this document will be
+exported as HTML. All the code in it will be re-executed, and the
+results will be retrieved and included into the exported document. If
+you do not want to re-execute all code each time, you can delete the #
+and the space before #+PROPERTY: in the header of this document.
+
+Like we showed in the video, Python code is included as follows (and
+is exxecuted by typing C-c C-c):
+
print("Hello world!") ++
+Hello world! ++ + +
+And now the same but in an Python session. With a session, Python’s
+state, i.e. the values of all the variables, remains persistent from
+one code block to the next. The code is still executed using C-c
+C-c.

+Finally, an example for graphical output: +
+
+
+ File “<stdin>”, line 1, in <module>
+ File “/tmp/babel-vQxa6K/python-Wy3IOy”, line 2, in <module>
+ import matplotlib.pyplot as plt
+ModuleNotFoundError: No module named ’matplotlib’]]
+
+Note the parameter :exports results, which indicates that the code
+will not appear in the exported document. We recommend that in the
+context of this MOOC, you always leave this parameter setting as
+:exports both, because we want your analyses to be perfectly
+transparent and reproducible.
+
+Watch out: the figure generated by the code block is not stored in
+the org document. It’s a plain file, here named cosxsx.png. You have
+to commit it explicitly if you want your analysis to be legible and
+understandable on GitLab.
+
+Finally, don’t forget that we provide in the resource section of this
+MOOC a configuration with a few keyboard shortcuts that allow you to
+quickly create code blocks in Python by typing <p, <P or <PP
+followed by Tab.
+
+Now it’s your turn! You can delete all this information and replace it +by your computational document. +
