Add a brief description of the print statement

[hjwp]

We start using print later on, but it hasn't been explained. This shows why you might want to use it instead of just letting the interpreter give you the repr of a variable.

Could go into more details on, eg, backslash-escaping of quotes, or print ('more\nthan\none\nline')...

I would prefer using name = 'Ola' rather than the traditional hello world.

I've found that it makes the participants subsitute their own name instead and they're more engaged as a result.

Merged in f89a5f7.

I changed message to name like I explained in my comment and edited the commit message slightly.
Hope that's OK.

Thanks again!
