- Everything should comply with PEP8. Code should pass
``pep8 --max-line-length=100`` without any warnings.
- **Indenting**:
- NEVER tabs. 4 spaces to indent.
- Max line width: 79 chars (with flexibility to overflow by a "few chars" if
the overflowing content is not semantically significant and avoids an
explosion of vertical whitespace).
- Use camel case for class and type names
- Use underscores for functions and variables.
- Use double quotes.
- Use parentheses instead of '\\' for line continuation where ever possible
(which is pretty much everywhere)
- There should be max a single new line between:
- statements
- functions in a class
- There should be two new lines between:
- definitions in a module (e.g., between different classes)
- There should be spaces where spaces should be and not where there shouldn't be:
- a single space after a comma
- a single space before and after for '=' when used as assignment
- no spaces before and after for '=' for default values and keyword arguments.
- Indenting must follow PEP8; either hanging indent or multiline-visual indent
depending on the size and shape of the arguments and what makes more sense to
the author. In other words, both this::

the previous, it's up to the author's discretion as to which layout makes most
sense for their function invocation. (e.g. if they want to add comments
per-argument, or put expressions in the arguments, or group related arguments
together, or want to deliberately extend or preserve vertical/horizontal
space)

- Comments should follow the `google code style
- **Line length**:
Max line length is 79 chars (with flexibility to overflow by a "few chars" if
the overflowing content is not semantically significant and avoids an

Use parentheses instead of ``\`` for line continuation where ever possible
(which is pretty much everywhere).
- **Naming**:
- Use camel case for class and type names
- Use underscores for functions and variables.
- Use double quotes ``"foo"`` rather than single quotes ``'foo'``.

There should be spaces where spaces should be and not where there shouldn't
be:
- a single space after a comma
- a single space before and after for '=' when used as assignment
- no spaces before and after for '=' for default values and keyword arguments.
- **Comments**: should follow the `google code style
