digits = range(10) # Built-in range(X) function generates lists up to but not including X

evens = range(0,10,2) # Optional arguments to range() can specify start, stop, and step

squares = [ x * x for x in range(100) ] # List comprehension expressions can create lists

digits.insert(0, digits.pop()) # List objects support various methods,

# .pop() removes and returns last item, .insert(index, item) does what you'd expect
