the `else` condition is given, it will run if none of the other conditions was truthy. In Python
the `if..elif..else` structure also serves the same function as `case` in some other languages.

- **Line 15** has our first _conditional_, an `if` statement. This is written on the form `if <condition>:` and only if that condition is 'truthy' will the indented code block under the `if` statement run. To learn what is truthy in Python it's usually easier to learn what is "falsy": - **Line 15** has our first _conditional_, an `if` statement.

To learn what is truthy in Python it's usually easier to learn what is "falsy":
- `False` - this is a reserved boolean word in Python. The opposite is `True`. - `False` - this is a reserved boolean word in Python. The opposite is `True`.
- `None` - another reserved word. This represents nothing, a null-result or value. - `None` - another reserved word. This represents nothing, a null-result or value.
- `0` or `0.0` - `0` or `0.0`
- The empty string `""` or `''` or `""""""` or `''''''` - The empty strings `""`, `''`, or empty triple-strings like `""""""`, `''''''`

- **Line 16**'s condition is `not args`. The `not` _inverses_ the result, so if `args` is the empty string (falsy), the whole conditional becomes truthy.
