super（）在Sublime Text中抛出一个错误，在PyCharm/Terminal中工作

Question

我已经将下面的代码作为赋值的一部分。

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终端运行它时，它工作得很好。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) 

为什么错误出现在Sublime中，但不是在PyCharm或Terminal中？

所需的输出：

0.047 
3.75

你sublimetext使用默认的编译系统，这是Python的2.配置能在Python运行3

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

添加这些内容：

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

用合理的fi保存配置例如python3.sublime-build，并在Tools -> Build With ...中选择这个新创建的版本。
