Minor change suggestion

in content/1.3_lists.md, line 116 (below for context)

mild_salsa = ['peppers', 'onions', 'cilantro', 'tomatoes']
hot_salsa = list(mild_salsa)        # <-- makes a *copy* of the list

I would suggest the following as more appropriate:

hot_salsa = mild_salsa.copy()

Similarly, with "If all we want to do is copy a (simple) list, we can again use the list function", the list.copy() method is designed explicitly for this and is arguably more intuitive.
