What does this code do in Python?

Question

I'm learning Python and ran into some code that has this line...

self.clear()

I am curious as to what it would do and why would someone need to do this?

Answer 1

That line calls the clear method on the current object. What the clear method actually does depends on what class this code is inside.

Answer 2

If you found it inside the function, that looked like:

def __parse(self,filename):

then you will probably find something similar to this:

def clear(self):

If you find it, there's the code, that will be executed within self.clear()

Answer 3

抱歉，如果它不是清除的，但我只是找到了clear（）的代码...所有操作都是在为它分配新值之前清除了UserDict对象。...我误解了代码，并以为编写者实际上正在删除当前对象....无论如何找到答案....感谢帮助人员....我将来会更加谨慎地询问我如何表达我的问题，尤其是首先不要问些什么。
