portions of the codebase. When in doubt, waivers to rules of this type can be sought by asking your project leads. This is specifically important for our codebase because code ownership and team membership your project leads to get additional input. Header Files In general, every .cc file should have an associated .h file. There are some com- mon exceptions, such as unittests and small .cc files containing use of header files can make a huge difference to the readability, size and performance of your code. The following rules will guide you through the various pitfalls of using header files. Self-contained

Definition: Container types, like dictionaries and lists, define default iterators and membership Decision: Use default iterators and operators for types that support them, like lists, dictionaries, and files. The built-in types define iterator methods, too. 7 Prefer these methods to methods that return
