passing parameter between functions on python

Question

I try to use a parameter of another function. I prefer to not use global variable. I try the following one, but I have an error. I search in google and here but I haven't found something to help me

class MainHandler(BaseHandler):
    def get(self):
        ******
        all_list = *a list*  
        ******

    def post(self):
        for i in self.all_list:
           if i[0] == something:
                   ****

And I have this error: AttributeError: 'MainHandler' object has no attribute 'all_list'

Answer 1

You need to set

self.all_list = *a list*

self is the instance that gets passed to the function, what you are doing at the moment is just setting a local variable to the function.
