TypeError: 'bool' object is not callable
<p>I am brand new to python. I got a error</p>

<pre><code>while not cls.isFilled(row,col,myMap):
TypeError: 'bool' object is not callable
</code></pre>

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

<pre><code>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 &lt; row:
            ## for-while
            j = 0
            while j &lt; col:
                if not myMap[i][j].getIsActive():
                    cls.isFilled = False
                j += 1
            i += 1
        return cls.isFilled
</code></pre>
