Another thing worthy putting there may be may be the three ways to do
`if` statements to compare stuff:

1. `if x` — runs bool(x), see list above, can be negated by `if not x`
2. `if x == y` — tests if they have the same value, negated by `if x
!= y` or `if not x == y` (not used).
3. `if x is y` — tests if they are the same object, used for `is
None`/`is not None` comparisons and not much else.
