"List object is not callable" Python Error

Question

I'm working on a Python Image Library project for fun. I cannot however, figure out why I keep getting a "list not callable" error for this code:

def __computeTopColors(self):
    temp1, temp2, temp3, temp4 = [], [], [], []

    max = (0,0,0)
    for v in self.PixelVals: 
        if (v[0] > max[0]) and (v[1] > max[1]) and (v[2] > max[2]):
            max = v

    min = (1000,1000,1000)
    for v in self.PixelVals:
        if (v[0] < min[0]) and (v[1] < min[1]) and (v[2] < min[2]):
            min = v

    for pval in self.PixelVals:
        if (min[0] <= pval[0] <= int(((max[0])/2))) and (min[1] <= pval[1] <= int(((max[1])/2))):
            temp1.append(pval) 

    return temp1

def temp(self): 
    print self.temp

Note: This is actually an excerpt from a class, but I don't think that's particularly relevant. self.PixelVals is a list tuples of the form (R,G,B). self.temp is a temporary method I'm using to test the __computeTopColors method; I set self.temp equal to self.__computeTopColors in __init__.

The Traceback :

Traceback (most recent call last):
  File "fiveColors.py", line 39, in <module>
    a.temp()

Line 39 is the last line in my code block.

Answer 1

You've shadowed int with a list somewhere. Stop doing that. And stop shadowing min() and max() while you're at it.
