Sense Function

Question:

Start Quiz:

#Modify the code below so that the function sense, which 
#takes p and Z as inputs, will output the NON-normalized 
#probability distribution, q, after multiplying the entries 
#in p by pHit or pMiss according to the color in the 
#corresponding cell in world.


p=[0.2, 0.2, 0.2, 0.2, 0.2]
world=['green', 'red', 'red', 'green', 'green']
Z = 'red'
pHit = 0.6
pMiss = 0.2

def sense(p, Z):
    #
    #ADD YOUR CODE HERE
    #
    return q

print sense(p,Z)

world=['green', 'red', 'red', 'green', 'green']
Z = 'red'
pHit = 0.6
pMiss = 0.2

def sense(p, Z):
    
    p = [p[i] * (( (world[i] == Z) * pHit) + (world[i] != Z) * pMiss) for i in range(len(p))]
    
    return p

print sense(p,Z)
