python pep8:e305

PEP 8是Python编程规范的一部分，其中包括了命名规范、注释规则和编程推荐等内容。错误信息PEP 8: E305 expected 2 blank lines after class or function definition, found 1意味着在函数定义后只有一个空行，但是规范要求在函数定义后添加两个空行。

解决这个问题的方法很简单，只需要在函数定义后面添加两个空行即可。这样就符合了PEP 8的要求，也能解决错误信息中提到的问题。

如果你遵循了PEP 8编码规范，不仅能提高代码的可读性，也能让你的代码更加规范和易于维护。你可以下载PEP 8编程规范的文档，详细了解其中的内容和建议。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
