Extend this for function arguments:

However, there is a convention that is followed by most Python code: a 
name prefixed with an underscore (e.g. _spam) should be treated as a 
non-public part of the API (whether it is a function, a method or a data 
member). It should be considered an implementation detail and subject to 
change without notice.
