object returned by the function calls the superclass method, rather than the method of the current class. The super function will return a super object, which is responsible for method parsing. During the parsing process, it will automatically find all parent classes and parent classes of the parent class. Method 1 is more intuitive, and method 2 can initialize

Python subclass calls the parent class method, and python calls the Class Method During Python inheritance, if the subclass overrides the init () function, the init () of the parent class will not be called. In this case, if the s

In fact, there is no difficulty. Because of the popularity of

sys statement in a Python script and then executing it. Next, I will use SYS. Path. append to set the default search path to the current one. Of course, you can set it to another path, either relative or absolute. Then I made a print. See what these paths are. Or you can directly put the script (. py) file you have written that will be called in CC ++ into any path. In the subsequent loading module function
