# Variable naming
- Must
  - start with `_ a-z A-Z`
  - followed can use `_ 0-9 a-z A-Z`
  - cannot be reserved words

- Convertions
  - `_my_var` :  This is a convention to indicate orvgte objects Objects named this way will not get imported by a statement such as: `from module tmport`
  - `__my_var` : Used to 'mangle" class attributes useful in inheritance chains
  - `__my_var__` : Used for system-defined names that have a special meaning to the interpreter.
  - Packages : short, all-Howercase names. Preferably no underscores. e.g. `utilities`
  - Modules : short, allHowercase names. Can have underscores. e.g. `db_var`
  - Classes : CapWords (upper camel case) convention, e.g. `MyClass`
  - Functions lowercase, words separated by underscores (snake_case) e.g. `my_func`
  - Variables lowercase, words separated by underscores (snake case) e.g. `my_var`
  - Constants all-uppercase, words separated by underscores. e.g. `CONT_A`
