My thinking is that if i run from controller class "main" it will allow me to take the "data" from Class "model", def "filename". It doesn't seem to work. As you can see below what i mean

class Controller:
    def __init__(self):
        self.model = Model()
        self.view = View()
    def main(self):
        data = self.model.filename()
        self.view.tcpdump(data)
class View:
    def tcpdump(self, command):
        subprocess.call(command.split(), shell=False)

When i run my code i get this error:

subprocess.call(command.split(), shell=False)
AttributeError: 'NoneType' object has no attribute 'split'

My guess means that its not picking up command (look at source for reference) or that its not getting command with variables. But i know the error when variables are not being picked up so i don't think it is that.

My question is, from what i have thus far, how do i from "class view" grab "command" for my subprocesses to run.

Thanks~
