Python Naming conventions

Google Open source project style guide: http://zh-google-styleguide.readthedocs.io/en/latest/reference: http://www.cnblogs.com/zhanglianbo/p/ 5664997.html naming

Module_name, Package_name, ClassName, Method_name, Exceptionname, Function_name, Global_var_name, Instance_var_name, Function_parameter_name, Local_var_name.

Names that should be avoided

1. Single-character names, in addition to counters and iterators.
2. Hyphen (-) in Package/module name
3. A name that begins and ends with a double underscore (python reserved, for example __init__)

Naming conventions

1. The so-called "internal (Internal)" means that only modules are available within the module, or that they are protected or private within the class.
2. Starting with a single underscore (_) indicates that a module variable or function is protected (not included when using import * from).
3. An instance variable or method that begins with a double underscore (__) represents a private in-class.
4. Place related classes and top-level functions in the same module. Unlike Java, there is no need to restrict a module to a class.
5. Words that begin with a capital letter for the class name (such as capwords, Pascal style), but the module name should be underlined in lowercase (such as lower_with_under.py). Although there are already many existing modules that use a name similar to capwords.py, it is now discouraged because if the module name happens to coincide with the class name, it can be confusing.
