So, I've tried a few ways to make it print all the values but it's not working... Can someone help please?

 from myro import*
init("simulator")

lightLeft = getLight("left")
lightCenter = getLight("center")
lightRight = getLight("right")

def pressC():
    key = "x"
    while key != "C":
        key = raw_input("Enter C to continue: ")


def main():
    senses()
    pressC()
	
    Leftsensorvalues = []
    Centersensorvalues = []
    Rightsensorvalues = []
    
    forward(1,1)
    
    for i in range(20):
        turnLeft(.35,1)
        lightLeft
        Leftsensorvalues.append(lightLeft)
        
        lightCenter
        Centersensorvalues.append(lightCenter)
        
        lightRight
        Rightsensorvalues.append(lightRight)
    
    print "Left Sensor Values:" + str(Leftsensorvalues)
    print "Center Sensor Values:" + str(Centersensorvalues)
    print "Right Sensor Values:" + str(Rightsensorvalues)
	
    Leftaverage = sum(Leftsensorvalues) / 15
    Centeraverage = sum(Centersensorvalues) / 15
    Rightaverage = sum(Rightsensorvalues) / 15
	
    print "Left average:" + str(Leftaverage)
    print "Center average:" + str(Centeraverage)
    print "Right average" + str(Rightaverage)

main()

I do not know myro. So just a wild guess:

In line 26 (also in 29, 32) you actually wanted to write:

lightLeft = getLight("left")

Just writing

lightLeft

does nothing. It is just a variable name and you do nothing with it.
So in your next line

Leftsensorvalues.append(lightLeft)

only the value you read at the very beginning gets appended to your list.
