from file import function。不需要文件扩展名或函数参数 您可能应该阅读Python教程中的模块部分。 只要确保使用pycharms,它就只能识别下划线分隔的文件名。 进口时不需要增加file.py。只需编写from file import function,然后使用function(a, b)调用函数。这可能不起作用的原因是file是Python的核心模块之一,所以我建议...

我们可以使用from file name import all命令读取它。这表明我们已经从提供的文件中导入了所有类。 在这种情况下,我们使用from file name> import *语句。该语句从文件中导入所有类,如下所示。 # pythonclassOperations:def__init__(self):self.sum=0defTo_sum(self, a, b):self.sum=a+breturnself.sumclass...
