要导入模块其实很简单,首先我们需要提供模块的文件名,注意,跟Python中导入模块一样,这里的文件名不能包含".py"后缀,比如我的文件名是python_code.py,我在程序中只需要提供"python_code"这个字符串就可以了。这一部分代码如下(注意使用到的两个函数:PyString_FromString和PyImport_Import): PyObjec
To create a constructor in Python, use the __init__ method within a class. This special method is automatically called when an object is instantiated, initializing the instance variables. For example, class Car: def __init__(self, make, model): self.make = make; self.model = model init...
