# get some lists
# lists are NOT functions, they are a data type that holds multiple values
# functions get parentheses, lists and sequences get brackets
# lists and string indices/slices work the same way, both start indexing at 0
# brackets are nowhere in functions, brackets are exclusive to sequences

s = "We Are In It Together"

values = [ ] # empty list
# if you are going to build a list... maybe even in a for loop... we'll definitely never do that (this is a lie)
# empty lists are incredibly useful in programming, we'll build lists using accumulation
# when accumulating a list, you start out with an empty list []
# when accumulating a total, start with 0

stuff  = [ 'abc', 1112, 2.71, ] # lists can hold multiple different data types in python

digits = [ 3, 1, 4, 1, 5, 9, 2, 6 ]
# we can use operators in lists, but we avoid it in 1112, as python is special in this regard
# when people use operators on tests, code blows up... no one likes that

words  = s.split() # words is a list produced from splitting s on whitespace
# we can add on to lists after making them with the append() method function

# determine their sizes

vlen   = len( values ) # calculates the length of a sequence - for a list, returns the number of elements

# GOTCHA: max/min does not look at string length!!
