cannot import function from file in same directory

I have the following code:

from fitnessFunction import labDistance

The fitnessFunction.py folder is in the same directory, and has this code

def labDistance(self,createdRGB, realRGB):
    createdLAB = color.rgb2lab(createdRGB)
    realLAB = color.rgb2lab(realRGB)

    cLAB = createdLAB.reshape(createdLAB.shape[0]*createdLAB.shape[1],3)
    rLAB = realLAB.reshape(realLAB.shape[0]*realLAB.shape[1],3)

    distance = 0
    for i in range(cLAB.shape[0]):
        deltaX = cLAB[i][0] - rLAB[i][0]
        deltaY = cLAB[i][1] - rLAB[i][1]
        deltaZ = cLAB[i][2] - rLAB[i][2]
        delta = math.sqrt(deltaX**2 + deltaY**2 + deltaZ**2)
        distance = distance + delta
    
    return -1*distance

However I get the following error when importing...

cannot import name 'labDistance' from 'fitness'

You have to change from

from fitnessFunction to from .fitnessFunction in order to specify that you are importing it from a local file
