Receiving following error when trying to write Python3 program: NameError: name 'util' is not defined

Question

Trying to write a Python code and keep getting the following error message, *** NameError: name 'util' is not defined for this snippet of code. Cannot figure out the problem.

code

import itertools
import random
import busters
import game

from util import manhattanDistance, raiseNotDefined

def getBeliefDistribution(self):
        """
        Return the agent's current belief state, a distribution over ghost
        locations conditioned on all evidence and time passage. This method
        essentially converts a list of particles into a belief distribution.

        This function should return a normalized distribution.
        """
        "*** YOUR CODE HERE ***"
        beliefDistribution = util.Counter()

        for particle in self.particles: #in particle list
            beliefDistribution[particle] += 1 #weighing all the particles
        beliefDistribution.normalize() #normalizing

        return beliefDistribution #returns distribution

        #util.raiseNotDefined()

Where's the `util.py` file? Same folder as this code? Or is it some library? — Kevin Languasco, Apr 17 '20 at 00:25
