New Pulp code should adhere as closely as is reasonable to PEP-8. One modification is that our line length limit is 100 characters, which we chose to prevent line wrapping on GitHub.
It is recommended to enable flake8 in your text editor.
You should also place
setup.cfg file in top directory with all pulp content,
which will look like this:
[flake8] ignore = D203 max-line-length = 100
All new code must have a doc block that describes what the function or class does, describes each of the parameters and its type (fully qualified please), lists exceptions that can be raised, and describes the return value and its type.
def update(title, author, book): """ Updates information about a book and returns the updated object. :param title: new title the book should be assigned :type title: basestring :param author: new author that the book should be assigned :type author: fully.qualified.author :param book: book object that will be updated :type book: fully.qualified.book :raises BookNotFound: if book is not found :return: updated book object :rtype: fully.qualified.book """ if book is None: raise BookNotFound _do_update(title, author, book) return book
More details on the markup is described here.
Include reasonable in-line comments where they might be helpful.
Use meaningful names.
def update(t, n, p):
def update(title, name, path):
Be mindful of the global namespace, and don’t collide with builtins and standard library components. For example, don’t name anything “id”, “file”, “copy” etc.
4 spaces, never tabs
Specify UTF-8 encoding in each file:
