Student.print_marks(88) # Output: Obtained Marks: 88 classmethod() Syntax The syntax of classmethod() method is: classmethod(function) classmethod() is considered un-Pythonic so in newer Python versions, you can use the @classmethod decorator for classmethod definition. The syntax is: @classmetho...
'Student_marks': {'English': 88, 'maths': 92, 'science': 95, 'social_science': 65}, 可以清楚看到pprint的优势之处,数据结构一目了然啊。 三、Python Debugger 交互式调试器也是一个神奇的函数,如果在运行代码单元格时出现报错,可以在新行中键入%debug运行它。这将打开一个交互式调试环境,自动转到报...
