`or` has another meaning in Python, and many other languages:
flag = len(mystring) > 10 or count < 50
By the way, if you're testing a single name against a series of
alternatives, it is often better to look up the value in a dictionary:
table = {bar: 23, baz: 42, boop: 73, beep: 124}
value = table[foo]
instead of:
if foo == bar:
value = 23
elif foo == baz:
value = 42
elif ...
You can even provide a default value by using table.get().
