You have used convert_int as for an instance method in the class.

class Abc(object):
    def __init__(self,words):
        self.words = words

    def convert_int(self, s): #updated
        try:
            return int(s)
        except ValueError:
            return s
    def test(self):
        words = self.words
        words = self.convert_int(words) #updated
       return words
f = Abc("12345")
print(f.test())
