Number of lines of code in a function or method definition.
Depending on the value of method_length_count_comment,
comments are considered. The rule of 30
suggests that the maximum number of lines for a method is 30.
defines a default value of 100 lines per method, checkstlye` 150 and
60 (when comments are not considered),
||Represents the max number of lines for a method or a function'sdefinition.||30, 10, 50, 60, 100|
||Allows when set to True to considered comments while calculatingmethods' length.||60, 30, 100, 150|
* bold denotes default value
This aspect does not have any sub aspects.
def _is_positive(num): if num > 0: return True else: return False # This function can be defined as follow: def is_positive(num): return num > 0
It is really important is to stay DRY ("Don't Repeat Yourself") and respect separation of concerns. Long methods are sometimes faster and easier to write, and don't lead to maintenance problems. But most of the time they are an easy way to detect that something may be wrong in the code, and that special care is required while maintaining it.
How to fix this
Refactoring methods into smaller more generic methods, making code more compact by using inline and language specific syntax tricks, implementing methods or functions to avoid redundant operation(s), making use of methods provided in libraries rather than reimplementing them.
