super()在Sublime Text中抛出错误,在PyCharm/Terminal中工作

Question

我作为作业的一部分制作了以下代码.

class Question:
    """Base class for all questions"""

    question_count = 0

    def __init__(self, desc):
        self.desc = desc

        Question.question_count += 1


class MarkovMM(Question):
    def __init__(self, desc, arrival, service):
        super().__init__(desc)
        if self.desc == "Question 2":
            self.answer = round(1 - (1 - (arrival / service)) - ((1 - (arrival / service)) * (arrival / service)), 3)
        elif self.desc == "Question 3":
            self.answer = round(1 / ((service / 60) - (arrival / 60)), 4)

qu2 = MarkovMM("Question 2", 5, 23)
print(qu2.answer)
qu3 = MarkovMM("Question 3", 6, 22)
print(qu3.answer)

当我通过PyCharm和Ubuntu终端运行时,它运行正常.但是,在Sublime Text中运行它会产生以下错误.

Traceback (most recent call last):
  File "/home/estilen/Dropbox/College/Year_3/CSA2/Python/hello.py", line 20, in <module>
    qu2 = MarkovMM("Question 2", 5, 23)
  File "/home/estilen/Dropbox/College/Year_3/CSA2/Python/hello.py", line 14, in __init__
    super().__init__(desc)
TypeError: super() takes at least 1 argument (0 given)

为什么Sublime出现错误,而PyCharm或Terminal出现错误？

期望的输出:

0.047
3.75

您的sublimetext使用默认的构建系统,即Python 2.将其配置为在Python 3中运行.

Tools -> Build System -> New Build System ...

添加此内容:

{
    "cmd": ["python3", "-u", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

例如python3.sublime-build,使用合理的文件名保存配置,然后选择此新创建的内置Tools -> Build With ....
