Basically, PEP8
|
|
|
|
- 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::
|
|
|
|
print("I am a fish %s" % "moo")
|
|
|
|
and this::
|
|
|
|
print("I am a fish %s" %
|
|
"moo")
|
|
|
|
and this::
|
|
|
|
print(
|
|
"I am a fish %s" %
|
|
"moo"
|
|
)
|
|
|
|
...are valid, although given each one takes up 2x more vertical space than
|
|
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 <http://google.github.io/styleguide/pyguide.html?showone=Comments#Comments>`_.
|
|
This is so that we can generate documentation with
|
|
`sphinx <http://sphinxcontrib-napoleon.readthedocs.org/en/latest/>`_. See the
|
|
`examples <http://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html>`_
|
|
in the sphinx documentation.
|
|
|
|
Code should pass pep8 --max-line-length=100 without any warnings.
