Those if/else are at global scope. An 'if' statement does not introduce
a new scope; so getDictValues, despite being "indented", is defined at
global scope, and may be used anywhere in the module.
Does that mean the rules would be different inside a function?
Yes: a function body *does* create a new scope, as well as the class
statement. See
