Takes exactly 3 arguments (4 given)

Question

i\'m refactoring code in order to add object orientation and am just testing the code.

pattern = r\"((([01]?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])[ (\\[]?(\\.|dot)         


        

Answer 1

You are giving self.getip() four arguments because Python automatically adds in first self argument for bound methods. The expression:

self.getip(self, pattern, line)

results in:

getip(self, self, pattern, line)

which is four arguments.

Don't pass in self again:

self.ip = self.getip(pattern, line)

The very act of looking up the method on the instance (via self.getip) binds the method to handle that first argument for you.

Answer 2

When calling an instance method, you don't pass the instance explicitly

ie.

self.ip = self.getip(pattern, line)
