# NFD code style guidelines

## C++ code style

NFD adopts the [ndn-cxx code style](https://named-data.net/doc/ndn-cxx/current/code-style.html).

## Python code style

Most of the provisions in the above style guidance apply to Python as well.  For python-specific elements, [PEP 8](https://www.python.org/dev/peps/pep-0008/) can be used as a reference coding style.

The following is few rules directly adopted from [PEP 8](https://www.python.org/dev/peps/pep-0008/):

* **P1**  Always surround these binary operators with a single space on either side: assignment (=), augmented assignment (+=, -= etc.), comparisons (==, <, >, !=, <>, <=, >=, in, not in, is, is not), Booleans (and, or, not).

        def complex(real, imag=0.0):

            value = 1.1

            return magic(r=real + value, i=imag)

* **P2** Don't use spaces around the = sign when used to indicate a keyword argument or a default parameter value.

        def complex(real, imag=0.0):

            return magic(r=real, i=imag)
