Rule Definition
It is common among software projects to agree on a maximum length for code lines. The main reason behind this restriction is to improve readability, especially when comparing line by line different versions of the same file. Widespread presence of long lines can also indicate the need of code refactoring. Python offers different solutions to wrap long statements that help enhancing the visual structure of the code.

Remediation
The first step is to wrap long statements trying to visually enhance at the same time its inner structure. As recommended in PEP-8: "The preferred way of wrapping long lines is by using Python’s implied line continuation inside parentheses, brackets and braces. Long lines can be broken over multiple lines by wrapping expressions in parentheses. These should be used in preference to using a backslash for line continuation." Nowadays IDEs can be configurated to automatically signal too long code lines and visualize length margins. When systematically finding the need to have long lines in a module, it should be considered code refactoring, in particular when highly nested code blocks, too large number of function parameters, or too long object names are found.

Violation Code Sample

castle = MakeBigCastle(rocks = rocks_from_the_mountain, wood = wood_from_the_forest, water = water_from_the_well)

Fixed Code Sample

castle = MakeBigCastle(rocks = rocks,
                                           wood = wood,
                                           water = water)
