由于在此没有讨论的原因,法典线对任何东西都是一种坏的衡量。 但是,在“灰色源代码”档案中,是否有计算这些说法的硬性办法?

最佳回答

图表在其产出报告中直接列出:

  pylint main.py 

  ...

  Report
  ======
  145 statements analysed.
问题回答

使用<条码>ast模块,使 s子树与代谢法形成。 你们将能够应用你希望以该树和 no为基础的定制计算算法。

实际编码线(而不是法典法) 我发现SLOCCount,以给出合理的数字。

虽然这是个老职位。 这里是一刀切的法典,用与PyLint相同的方式,用假冒的原始资料来计算这些陈述。

from astroid import MANAGER
# Tested with astroid 2.3.0.dev0

class ASTWalker:
    """
    Class to walk over the Astroid nodes
    """
    def __init__(self):
        self.nbstatements = 0

    def walk(self, astroid_node):
        """
        Recurse in the astroid node children and count the statements.
        """
        if astroid_node.is_statement:
            self.nbstatements += 1

        # recurse on children
        for child in astroid_node.get_children():
            self.walk(child)

walker = ASTWalker()
ast_node = MANAGER.ast_from_file("/my/file/name", source=True)
walker.walk(ast_node)

print(walker.nbstatements)
