# ### Creating a Python program (not on the notebook) -- _Optional_
# 
# 
# * Use SSH and connect to your Unix shell
# * Type `nano helloworld.py` to open `nano`, a (relatively easy to use) text editor, and create the file `helloworld.py`
# * In the text editor, type:
#     `print('Hello my dear friend!')`
# * Type Ctrl+X, to save the file and close the editor.
# * In the shell prompt, type `python helloworld.py` to see the outcome
# 
# 

# #### Exercise
# 
# Open and change the file `helloworld.py` to print your own message.

# ### Creating a self-executing Python program -- _Optional_
# 
# * Repeat the steps as above, but with the following change: In the first line of your program, type: `#!/usr/bin/python`
# * Save the file with the name `hello`
# * In the shell, type `chmod 700 hello`. This makes our file _executable_.
# * Finally type `./hello` and see what happens.
