'int' Object Is Not Callable Error In Class

In python 2.7, I am writing a class called Zillion, which is to act as a counter for very large integers. I believe I have it riddled out, but I keep running into TypeError: 'int'

Solution 1:

You have both an instance variable and a method named increment that seems to be your problem with that traceback at least.

in __init__ you define self.increment = 1 and that masks the method with the same name

To fix, just rename one of them (and if it's the variable name, make sure you change all the places that use it--like throughout the increment method)

One way to see what's happening here is to use type to investigate. For example:

>>> type(Zillion.increment)
<type'instancemethod'>
>>> z = Zillion('5')
>>> type(z.incremenet)
<type'int'>

Solution 2:

You have defined an instance variable in Zillion.__init__()

def__init__(self, digits):
        self.new = []
        self.count = 0self.increment = 1# Here!

Then you defined a method with the same name 'Zillion.increment()`:

defincrement(self):
    […]

So if you try to call your method like this:

big_number = Zillion()
big_number.increment()

.ìncrement will be the integer you have defined in .__init__() and not the method.

Solution 3:

Because you have a variable member self.increment，and it has been set to the 1 in your __init__ function.

z.increment represents the variable member which set to 1.

You can rename your function from increment to the _increment(or any other names), and it will works.
