3. An Informal Introduction to Python
As well as the while statement just introduced, Python uses a few more that we will encounter in this chapter.

4.4. break and continue Statements¶
The break statement breaks out of the innermost enclosing for or while loop:
In a for or while loop the break statement may be paired with an else clause. If the loop finishes without executing the break, the else clause executes.
4.9.1. Default Argument Values¶
The most useful form is to specify a default value for one or more arguments. This creates a function that can be called with fewer arguments than it is defined to allow. For example:
Function annotations are completely optional metadata information about the types used by user-defined functions (see PEP 3107 and PEP 484 for more information).
Name your classes and functions consistently; the convention is to use UpperCamelCase for classes and lowercase_with_underscores for functions and methods. Always use self as the name for the first method argument (see A
