[python] TypeError: 'bool' object is not callable

I am brand new to python. I got a error

while not cls.isFilled(row,col,myMap):
TypeError: 'bool' object is not callable

Would you please instruct how to solve this issue? The first "if" check is fine, but "while not" has this error.

def main(cls, args):
        ...
        if cls.isFilled(row,col,myMap):
            numCycles = 0

        while not cls.isFilled(row,col,myMap):
            numCycles += 1


def isFilled(cls,row,col,myMap):
        cls.isFilled = True
        ## for-while
        i = 0
        while i < row:
            ## for-while
            j = 0
            while j < col:
                if not myMap[i][j].getIsActive():
                    cls.isFilled = False
                j += 1
            i += 1
        return cls.isFilled

Actually you can fix it with following steps -

1. Do cls.__dict__
2. This will give you dictionary format output which will contain {'isFilled':True} or {'isFilled':False} depending upon what you have set.
3. Delete this entry - del cls.__dict__['isFilled']
4. You will be able to call the method now.

In this case, we delete the entry which overrides the method as mentioned by BrenBarn.
