Don't understand this TypeError: 'list' object is not callable

Question

I have file called im.py which contains a couple of functions and several classes. The first function and class are failing with

TypeError: \'list\'         


        

Answer 1

You cannot use the same name for both a method and an attribute; methods are just special kinds of attributes. Your class may have a user() method, but by setting the attribute user on the instance, Python will find that instead of the method when you try to access b.user:

>>> type(b.user)  # no call, just the attribute

You'll have to rename either the method or the attribute to not conflict. You could use a leading underscore for the list attribute, for example:

class FirstClass:
    def setdata_user(self):
        self._user = getdata_user()    
    def displaydata_user(self):
        print(self._user)
    def user(self):
        u = self._user[0]
        return u
    def gids(self):
        g = self._user[1]
        return g
    def home(self):
        h = self._user[2]
        return h
